ITEM 1 - BUSINESS.
         --------
General
- -------

         Keithley Instruments, Inc. is a corporation which was founded in 1946
and organized under the laws of the State of Ohio on October 1, 1955.  Its
principal executive offices are located at 28775 Aurora Road, Solon, Ohio
44139; telephone (216) 248-0400. References herein to the "Company" or
"Keithley" are to Keithley Instruments, Inc. and its subsidiaries unless the
context indicates otherwise.

Products
- --------

         Keithley Instruments, Inc. provides instrumentation to semiconductor
manufacturers, medical equipment manufacturers, and growth segments of the
electronics industry.  Scientists and engineers around the world use Keithley's
advanced hardware and software for measurement, test, data acquisition, and
control.  Although the Company's products vary in capability, sophistication,
use, size and price, they basically test, measure, and analyze electrical and
physical properties. As such, the Company considers its business to be in a
single industry segment.  For each of the last three fiscal years, more than
90% of the Company's revenue was derived from the sale of electronic test and
measurement instrumentation and data acquisition and analysis hardware and
software, which represents one class of similar products.

         The operating units and product groups of the Company are described
below:

         TEST INSTRUMENTATION GROUP. The Test Instrumentation Group supplies
instruments for benchtop and systems applications and automatic parametric test
systems (APT).  The Company's largest division, it is an internationally
recognized leader in sensitive instruments for measuring a wide range of
electrical properties such as voltage, resistance, current, capacitance and
charge.  APT products can be found in semiconductor fabrication facilities
throughout the world.  The Test Instrumentation Group is comprised of the
following major product lines whose models, except for APT products, generally
range in price from $1,000 to $10,000:

            SENSITIVE INSTRUMENTS.  This product group includes electrometers,
            picoammeters, sensitive digital voltmeters, micro-ohmmeters, and
            certain other instruments which are distinguished by their extreme
            sensitivity, resolution and accuracy as compared to the
            capabilities of conventional meters.  Sensitive instruments are
            used by scientists, engineers, and researchers for the study of
            materials, semiconductors, and superconductors.  Typical customers
            are industrial and government research laboratories, educational
            institutions, and electronics manufacturers.





                                       1
<PAGE>   4

            DIGITAL MULTIMETERS.  These instruments are used in the measurement
            of voltage, current and resistance, and other electrical parameters
            in applications not requiring the extreme sensitivity of scientific
            products.  The digital multimeter product line includes several
            models of general purpose and specialized multimeters which differ
            by their resolution, accuracy, sensitivity, physical size and
            ability to be integrated into a personal computer-based test
            system.  General purpose multimeters are used by engineers and
            technicians for manual measurements in research and design testing.
            Specialized multimeters can be used in automated tests requiring
            rapid or repetitive measurements for design and quality control.

            SWITCHES AND SOURCES.  Switching instruments are used to route
            electrical signals in test systems to measurement and source
            instrumentation.  This allows many devices or test points to be
            measured with a minimum number of instruments.  Switch products
            together with Sensitive, Digital Multimeter, Source, I-V and C-V
            instruments can be integrated into computer-based systems to
            provide flexible, automated testing and measurement. Switch
            products are sold to scientists and engineers in research,
            semiconductor and electronic manufacturing markets.

            Sources generate the precise voltage and currents needed to test
            electronic devices and investigate properties of materials.  Source
            products are sold to scientists and engineers in research,
            semiconductor and electronic manufacturing markets, especially
            where stable signals of low level current and voltage are needed.
            These sources can be interfaced with computers as part of an
            automated test system, or used manually on the laboratory bench.

            SOURCE MEASURE UNITS.  These are programmable instruments capable
            of sourcing and measuring voltage and current, thus replacing the
            functionality of four instruments with one reliable, compact unit.
            These versatile instruments cover a wide dynamic range of voltage
            and current and their combination of high speed and sensitivity
            have made these units ideal for engineers and scientists in the
            research, semiconductor, and electronics manufacturing customer
            groups.

            C-V (CAPACITANCE VERSUS VOLTAGE).  C-V products include
            high-frequency and quasistatic C-V meters, measurement and analysis
            software, and computer-based test systems.  C-V products are used
            by scientists and engineers in semiconductor manufacturing
            facilities, industrial and governmental research laboratories, and
            educational institutions to research, develop, and characterize
            semiconductor devices, materials and manufacturing processes.

            APT PRODUCTS are computer-based analog parametric testing systems
            that measure various electrical characteristics of semiconductor
            materials. The Company is  one of the leading suppliers of these
            systems for semiconductor production applications.  In production,
            the systems allow manufacturers to monitor quality control
            parameters





                                       2
<PAGE>   5
            during fabrication of integrated circuits to improve manufacturing
            yields.  In research, the systems are used to analyze the
            characteristics of semiconductor  materials in the development of
            integrated circuit devices.  The systems can also be used to
            develop integrated circuit manufacturing processes.  A typical
            system incorporates instrumentation and  software developed by the
            Test Instrumentation Group and computer hardware manufactured by
            others.  The APT Group integrates the system's major components
            and, in most cases, customizes the system to specification,
            installs and services the equipment and software, and provides
            customer training.  Selling prices for these products generally
            range from $50,000 to $250,000.

         PROCESS MONITORING GROUP. The Process Monitoring Group designs,
develops, manufactures and markets products based on the direct wafer
measurement or non-contact technology purchased from International Business
Machines in May, 1994.  During fiscal 1995, the division incurred costs to
develop and market the Quantox product, the first product in a planned family
of products to be developed by Keithley based on the non-contact technology.
Revenues from Quantox are expected to begin in the second half of fiscal 1996.

         RADIATION MEASUREMENTS DIVISION. The Radiation Measurements Division

New Products During Fiscal Year 1995
- ------------------------------------

         Several new products were introduced during fiscal 1995 including the
following:

         THE TEST INSTRUMENTATION GROUP introduced several new products
including the Model 2000 6 1/2-digit digital multimeter (DMM).  Ten times
faster than any other DMM in its class, the Model 2000 includes multipoint
scanning capability not found in any other DMM in its price range of under
$1,000.  Also introduced was the Model 6517 electrometer/high-resistance meter.
The 6517 is used in production test of electrical insulating materials and
other products such as polymer coatings and latex gloves where product
consistency and quality are critical.

         THE PROCESS MONITORING GROUP introduced the Quantox oxide
characterization system, the first product incorporating the non-contact direct
wafer measurement technology purchased from International Business Machines in
May, 1994.  While Quantox will not contribute to revenues until the second half
of fiscal 1996, it has generated a significant amount of customer interest
since its introduction at the Semicon-West trade show in July, 1995.

         THE RADIATION MEASUREMENTS DIVISION introduced the TRIAD Quality
Assurance (QA) for Windows software.  The TRIAD QA for windows software works
with the TRIAD Kit and a personal computer to perform quality assurance testing
on diagnostic x-ray generators for all modalities.

         THE KEITHLEY METRABYTE DIVISIONintroduced several new products
including VTX (Visual Test Extension) software.  VTX adds significant data
acquisition and analysis functions to Visual Basic for Windows allowing greater
flexibility and programming speed than the proprietary software currently
available.  Several new boards were introduced including the DAS-1800AO (Analog
Outputs) board.  Like all members of the DAS-1800 series, the DAS-1800AO
supports continuous, high-speed data acquisition under the familiar Windows
environment or DOS.  Also introduced during fiscal 1995 was the DASCard-1000
series of PCMCIA data acquisition cards for notebook computers.  Providing a
cost-effective solution for field applications, the DASCard-1000 can be
installed in seconds and permits a wide variety of low to mid-level data
acquisition applications, bringing data acquisition and analysis in the field
or on the factory floor.

Geographic Markets and Distribution
- -----------------------------------

         Substantially all of the Company's products are manufactured in Ohio
and Massachusetts and are sold throughout the world in many developed
countries. The Company's principal markets are the United States, Europe and
the Pacific Basin.

         In the United States, the Company's products are sold by the Company's
sales personnel, independent sales representatives and through direct marketing
and catalog mailings.  United States sales offices are located in Solon, Ohio;
Santa Clara, California and Taunton, Massachusetts.  The Company markets its
products directly in European countries in which it has a wholly owned sales
subsidiary and through distributors in other countries.  European



                                      5

subsidiaries have sales and service offices located in or near London, Munich,
Paris, Amsterdam, Zurich and Milan.  The Company also has a sales office in
Beijing, China.  Sales in markets outside the United States, Europe and China
are made through independent sales representatives and distributors.  The
Company's Japanese subsidiary supports independent sales representatives and
distributors in the Pacific Basin.

Sources and Availability of Raw Materials
- -----------------------------------------

         The Company's products require a wide variety of electronic and
mechanical components, most of which are purchased.  The Company has multiple
sources for the vast majority of the components and materials it uses; however,
there are some instances where the components are obtained from a sole-source
supplier.  If a sole-source supplier ceased to deliver, the Company could
experience a temporary adverse impact on its operations; however, management
believes alternative sources could be developed quickly. Although shortages of
purchased materials and components have been experienced from time to time,
these items have generally been available to the Company as needed.

Patents
- -------

         Electronic instruments of the nature the Company designs, develops and
manufactures are generally not patentable in their entirety.  Although the
Company holds patents with respect to certain of its products, it does not
believe that its business is dependent to any material extent upon any single
patent or group of patents, because of the rapid rate of technological change
in the industry.

Seasonal Trends and Working Capital Requirements
- ------------------------------------------------

         Although the Company is not subject to significant seasonal trends,
its business is cyclical and is somewhat dependent upon the semiconductor
industry in particular.  The Company does not have any unusual working capital
requirements.

Customers
- ---------

         The Company's customers generally are involved in engineering,
research and development, product testing, electronic service or repair, and
educational and governmental research.  During the fiscal year ended September
30, 1995 no one customer accounted for more than 10% of the Company's sales.
Management believes that the loss of any one of its customers would not
materially affect the sales or net income of the Company.





                                   6

Backlog
- -------

         The Company's backlog of unfilled orders amounted to approximately
$11,284,000 as of September 30, 1995 and approximately $7,742,000 as of
September 30, 1994.  It is expected that the majority of the orders included in
the 1995 backlog will be delivered during fiscal 1996; however, the Company's
past experience indicates that a small portion of orders included in the
backlog may be canceled.

Competitive Conditions
- ----------------------

         The Company competes on the basis of quality, performance, service,
warranty and price, with quality and performance frequently being dominant.
There are many firms in the world engaged in the manufacture of electronic test
and measurement instruments, some of which are larger and have greater
financial resources than the Company.  The Company's competitors vary between
product lines and certain manufacturers compete with the Company in multiple
product lines.  The Company's principal competitors are Hewlett-Packard
Company, Fluke Corporation, National Instruments, Inc., Data Translation, Inc.
and Advantest Corporation.


Research and Development
- ------------------------

         The Company's engineering development activities are directed toward
the development of new products that will complement, replace or add to the
products currently included in the Company's product line.  The Company does
not perform basic research, but on an ongoing basis utilizes new component and
software technologies in the development of its products.  The highly technical
nature of the Company's products and the rapid rate of technological change in
the industry require a large and continuing commitment to engineering
development efforts.  Product development expenses were $15,385,000 in 1995,
$11,551,000 in 1994 and $10,304,000 in 1993, or approximately 14%, 13% and 11%
of net sales, respectively, for each of the last three fiscal years.  Research
contracts are not obtained from customers, nor does the Company conduct any
research work under government development contracts.  During fiscal 1994, the
Company expensed $3,300,000 to acquire the right to develop and commercialize
direct wafer measurement technology from International Business Machines.

Government Regulations
- ----------------------

         The Company believes that its current operations and its current uses
of property, plant and equipment conform in all material respects to applicable
laws and regulations.  The Company has not experienced, nor does it anticipate,
any material claim or material capital expenditure in connection with
environmental laws and other regulations.

Employees
- ---------

         As of September 30, 1995, the Company employed 659 persons, 98 of whom
were located outside the United States.  None of the Company's employees are
covered under the terms of a collective bargaining agreement and the Company
believes that relations with its employees are good.

Foreign Operations and Export Sales
- -----------------------------------

         Information related to foreign and domestic operations and export
sales is incorporated by reference to Note J of the Notes to the Consolidated
Financial Statements on page 31 of the Company's 1995 Annual Report to
Shareholders, a copy of which is filed as Exhibit 13 to this report.

         The Company has significant revenues from outside the United States
which increase the complexity and risk to the Company.  These risks include
increased exposure to the risk of foreign currency fluctuations and the
potential economic and political impacts from conducting business in foreign
countries.  With the exception of changes in the value of foreign currencies
which is not possible to predict, the Company believes that its foreign
subsidiaries and other larger international markets are in countries where the
economic and political climate is generally stable.

(2)       In connection with the adoption of Statement of Financial Accounting 
          Standards No. 109, "Accounting for Income taxes" (FAS 109), a
          valuation allowance was recorded for that portion of foreign tax
          credit carryforwards and other tax credit carryforwards recorded as
          deferred tax assets, where it is more likely than not these credits
          will not be utilized.  $3,316 was recorded as of October 1, 1992 and
          represented the cumulative effect of adoption of FAS 109, while $2 was
          recorded in the 1993 income tax provision as a reversal of    
          previously recorded valuation allowance.

</TABLE>
RESULTS OF OPERATIONS (IN THOUSANDS OF DOLLARS EXCEPT FOR PER SHARE DATA)

1995 COMPARED WITH 1994

Net income in 1995 was $4,914, or $.64 per share on a fully diluted basis,
compared with $907, or $.13 per share, in 1994.  Net income per share reflects
a two-for-one stock split to shareholders of record on November 27, 1995,
approved by the company's board of directors on November 6, 1995.  Net income
in 1995 included approximately $6,900 pretax in spending to develop our direct
wafer measurement technology purchased from International Business Machines
(IBM) in 1994 and explore other new growth opportunities.  1994's pretax income
included costs of $3,300 to purchase the technology, approximately $1,400 in
development costs and $925 in other non-recurring charges.

Record net sales of $109,574 increased 23 percent from $89,248 in 1994.
Increased demand from customers because of their own growth, particularly those
in the semiconductor industry, accounted for the increase.  Although net sales
benefited from an 11 percent weakening of the U.S. dollar against European
currencies, this benefit
<PAGE>   5
was offset by increased sales discounts due mainly to sales mix.
Geographically, net sales increased domestically by $7,606 or 17 percent,
export sales increased $5,168 or 38 percent, mainly in the Pacific Basin, and
European sales increased $7,552 or 25 percent, due in part to the weakening
U.S. dollar.

Cost of goods sold decreased to 38.7 percent of net sales compared to 39.5
percent in 1994.  The decrease was due mainly to an 11 percent weakening of the
U.S. dollar.  The effect of foreign exchange hedging on cost of goods sold was
to increase cost of goods sold as a percentage of net sales by 0.2 percentage
points in 1995.

Selling, general and administrative expenses increased $6,180 or 16 percent to
$43,945 from $37,765 in 1994, but decreased as a percentage of net sales to
40.1 percent from 42.3 percent.  The increase in expense was due mostly to
higher marketing costs associated with new business initiatives and the
introduction of new products from existing businesses, higher commissions due
to increased sales and an 11 percent weakening of the U.S. dollar.

Product development expenses increased $3,834 or 33 percent to 14.0 percent of
net sales compared to 13.0 percent of net sales in 1994.  Almost two-thirds of
the increase was due to additional spending to develop the direct wafer
measurement technology into our Quantox(TM) product.  We introduced Quantox in
July at SEMICON-West, a major semiconductor capital equipment trade show.
Initial customer reception has been positive, and we expect Quantox revenues
beginning in the second half of fiscal 1996.  The remainder of the increase in
product development expenses was primarily spent developing products for our
semiconductor customers.

Financing expenses (net of investment income) increased $165 to $986 from $821
in 1994, due mainly to higher average debt levels during 1995.

The effective income tax rate was 23.5 percent for 1995.  The lower than
statutory rate was due primarily to utilization of foreign tax credits and
foreign sales corporation (FSC) benefits.  The tax benefit recorded in 1994
also resulted from the utilization of foreign tax credits and FSC benefits.  At
September 30, 1995, the company had capital loss carryforwards of $277 and tax
credit carryforwards of $1,849.
<PAGE>   6

The company's financial results are affected by foreign exchange rate
fluctuations.  Generally, a weakening U.S. dollar causes the price of the
company's product to be more attractive in foreign markets and favorably
impacts the company's foreign sales and earnings.  A strengthening U.S. dollar
has an unfavorable effect.  This foreign exchange effect cannot be accurately
estimated since many other factors affect the company's foreign sales and
earnings.   These factors include product offerings and pricing policies of the
company and its competition, whether competition is foreign or U.S. based,
changes in technology and local and worldwide economic conditions.

From time to time, the company utilizes hedging techniques designed to mitigate
the effect of exchange rate fluctuations on operations and balance sheet
position by entering into forward and option currency contracts and by
borrowing in foreign currencies.  The company's use of forward and option
contracts limits exchange rate exposure and fixes exchange rates for its
foreign businesses.  The company's foreign borrowings are a hedge of its net
investments.  The company does not speculate in foreign currencies or
derivative financial instruments, and hedging techniques do not increase the
company's exposure to foreign exchange rate fluctuations.


Liquidity and Capital Resources
- -------------------------------

In 1995, net cash provided by operating activities of $2,457 was used
principally for investments in capital equipment of $2,695.  The company's
total debt at the end of 1995 increased by $1,297 to $6,113, compared to $4,816
at the end of 1994.  Total debt-to-capital at year-end was 14.2 percent,
compared to 13.1 percent last year.  Due to timing factors, cash at September
30, 1995 was $3,890, an increase of $1,178 during the year.

At September 30, 1995, the company had total unused lines of credit with
domestic and foreign banks aggregating $25,588, of which $6,539 were short-term
and $19,049 were available for long-term borrowings.  During 1996, the company
expects to finance capital spending and working capital requirements with cash
provided by operations and long-term borrowings.  1996 expenditures for capital
equipment additions are expected to be higher than the 1995 level as additional
property, plant and equipment may be necessary to support future growth from
new products and new business initiatives.

1994 COMPARED WITH 1993

Net income was $907, or $.13 per share, in 1994, compared with $4,784, or $.68
per share, in 1993.  Net income per share reflects a two-for-one stock split to
shareholders of record on November 27, 1995.  1994's net income includes $3,300
pretax for the purchase of direct wafer measurement technology from IBM, as
well as approximately $1,000 in incremental costs to begin to develop the
technology.  1994's costs also include $925 in "Selling, general and
administrative expenses," relating to the retirement of the company's former
president.  1993's net income includes the cumulative effect of adopting
Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes," (FAS 109) of $1,447, or $.21 per share.  Also included in fiscal 1993
are special charges of $1,046 pretax for severance and other costs related to
the August 1993 workforce reduction.

Net sales of $89,248 were two percent below $91,146 in 1993.  Sales volume was
down slightly from year to year.  A two percent strengthening of the U.S.
dollar against European currencies and higher discounts caused the decrease.
Geographically, an increase in sales of $3,159, or 48 percent to the Pacific
Basin, almost half of which was due to sales to the semiconductor industry of
automatic parametric test systems, was more than offset by lower sales
domestically and in Europe.  Lower domestic sales can be attributed to higher
than average sales volume for automatic parametric test systems in 1993, lower
1994 sales in the personal computer based data acquisition products, and
uncertainty in health care which caused a sales decline in the Radiation
Measurements Division.  The decline in Europe is due mainly to the
strengthening of the U.S. dollar versus foreign currencies.

Cost of goods sold increased to 39.5 percent of net sales compared to 37.9
percent in 1993.  The increase was due primarily to lower gross margins in
Europe due to the two percent strengthening of the U.S. dollar and higher sales
of lower margin products worldwide.  The effect of foreign exchange hedging on
cost of goods sold was not material in 1994.

Selling, general and administrative expenses decreased $651 or two percent to
$37,765 from $38,416 in 1993.  The decrease is due to lower costs in 1994 as a
result of the August 1993 workforce reduction, partially offset by $925 in
expenses related to the retirement of the company's former president.
<PAGE>   8
Product development expenses increased $1,247 or 12 percent to 13.0 percent of
net sales compared to 11.3 percent of net sales.  Approximately $1,000 of the
increase is due to additional spending to develop the direct wafer measurement
technology acquired during the third quarter of fiscal 1994.

Purchased technology of $3,300 represents the direct wafer technology rights
acquired from IBM.  Per the provisions of the purchase agreement with IBM, the
company will also pay future royalties based on specified sales levels.  There
is no minimum royalty payment required; however, $3,000 must be paid by May 26,
2000 to retain exclusive rights to the technology.

Special charges of $(42) recorded in 1994 represent the reversal of 1993's
accrual for expenses related to the August 1993 workforce reduction.  $1,046
was recorded in fiscal 1993 for this workforce reduction.  At September 30,
1994, the accrual recorded on the company's balance sheet was $0.

Financing expenses (net of investment income) were flat in 1994 versus 1993.
Reduced interest costs due to the lower debt levels were offset by lower
interest income and higher interest expense for the company's corporate-owned
life insurance.

The company recorded an income tax benefit in 1994.  The tax benefit resulted
from the utilization of foreign tax credits and FSC benefits.  The higher than
statutory rate for 1993, 39.7 percent versus 34.0 percent, resulted from the
company's inability to utilize certain tax credits and the non-deductibility of
goodwill amortization.

NOTES TO CONSOLIDATED

FINANCIAL STATEMENTS
(In Thousands of Dollars Except for Per Share Data)

NOTE A - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

      The consolidated financial statements include the accounts of Keithley
Instruments, Inc. and its subsidiaries.  Intercompany transactions have been
eliminated.  Certain items have been reclassified to conform to the 1995
presentation.

REVENUE RECOGNITION

      Sales are recognized at time of shipment for all products.

PRODUCT DEVELOPMENT EXPENSES

      Expenditures for product development are charged to expense as incurred.
These expenses include the cost of computer software, an integral part of
certain products.  Costs defined by Statement of Financial Accounting Standards
No. 86, "Accounting for the Costs of Computer Software to Be Sold, Leased, or
Otherwise Marketed," are immaterial to the financial statements and have been
expensed as incurred.  The company continually reviews the materiality and
financial statement classification of computer software expenditures.

INVENTORIES

      Inventories are stated at the lower of cost (determined by the first-in,
first-out method) or market.

PROPERTY, PLANT AND EQUIPMENT

      Property, plant and equipment are stated at cost.  Depreciation is
provided over periods approximating the estimated useful lives of the assets.
Substantially all manufacturing, laboratory and office equipment is depreciated
by the double declining balance method over periods of 3 to 10 years.
Buildings are depreciated by the straight-line method over periods of 23 to 45
years.  Leasehold improvements are amortized over the terms of the leases.
<PAGE>   10
INTANGIBLE ASSETS

      Intangible assets relate to business acquisitions and are amortized on a
straight-line basis over their estimated useful lives, ranging from 2 to 20
years.  Management reviews the carrying value of intangible assets using an
estimated future cash flow method (undiscounted and without interest charges)
whenever events or changes in circumstances indicate that the carrying amount
of the assets may not be recoverable.  Prior to 1995, the company used a
discounted cash flow method.

OTHER ASSETS

      Included in the "Other assets" caption of the Consolidated Balance Sheet
at September 30, 1995 and 1994, were $4,827 and $4,013, respectively, in
deferred tax assets.  Also included in "Other assets" were pension related
assets.  (See note E.)

      The "Net cash provided by operating activities" caption of the
Consolidated Statement of Cash Flows at September 30, 1994 included proceeds of
$2,503 from redeeming cash surrender value from the company's corporate-owned
life insurance program.  The remaining cash surrender value is classified in
"Other assets."

OTHER ACCRUED EXPENSES

      Included in the "Other accrued expenses" caption of the Consolidated
Balance Sheet at September 30, 1995 and 1994, were $1,522 and $1,187,
respectively, for commissions payable to outside sales representatives of the
company.

INCOME TAXES

      In the fourth quarter of 1993, the company adopted the provisions of
Statement of Financial Accounting Standards, No. 109 "Accounting for Income
Taxes," effective October 1, 1992.  The statement requires that deferred taxes
be established for all temporary differences between the book and tax bases of
assets and liabilities, measured using enacted tax rates and laws that will be
in effect when the differences are expected to reverse.

      Provision has been made for estimated United States and foreign
withholding taxes, less available tax credits, for the undistributed earnings
of the non-U.S. subsidiaries as of September 30, 1995.
<PAGE>   11
STOCK SPLIT/NET INCOME PER SHARE

         On November 6, 1995, the company's board of directors approved a
two-for-one split of the company's Common Shares and Class B Common Shares.
The split was effected in the form of a stock dividend payable on December 11,
1995, to shareholders of record on November 27, 1995.  All share and per share
amounts have been adjusted to reflect the stock split on a retroactive basis.

      The weighted average number of shares outstanding used in determining net
income per share restated for the stock split was 7,476,138 (7,719,776 on a
fully diluted basis) in 1995, 7,087,654 in 1994 and 7,060,838 in 1993.  Both
Common Shares and Class B Common Shares are included in calculating the
weighted average number of shares outstanding.  Net income per share on a fully
diluted basis was not materially different than net income per share in 1994
and 1993.

HEDGING AND RELATED FINANCIAL INSTRUMENTS

         The company utilizes foreign currency borrowings and foreign exchange
contracts to hedge foreign exchange risks for sales denominated in foreign
currencies and net equity or unremitted foreign earnings.

         To hedge sales, the company purchases foreign exchange contracts to
sell foreign currencies to fix the exchange rates related to near-term sales
and the company's margins.  Underlying hedged transactions are recorded at
hedged rates, therefore realized and unrealized gains and losses are recorded
when the operating revenue and expenses are recorded.

         To hedge equity or unremitted earnings, the company borrows foreign
currencies or purchases foreign exchange contracts.  Realized and unrealized
after-tax gains or losses on the hedging instruments are reflected in the
cumulative translation adjustment component of shareholders' equity.

         The company has entered into swap instruments to mitigate the risk of
interest rate changes.  The amounts exchanged under the swap agreements are
included in the "Financing expenses (net of investment income)" caption of the
Consolidated Statement of Income.  The
<PAGE>   12
estimated fair value of the swap instruments are determined through quotes from
the related financial institution.

         The company is exposed to credit loss in the event of nonperformance
by the counterparties to these financial instruments.  Because the
counterparties are major financial institutions, the company does not expect
such nonperformance.

NOTE B - PURCHASED TECHNOLOGY AND SPECIAL CHARGES

      In 1994, the company expensed $3,300 to acquire the right to develop and
commercialize direct wafer measurement technology from IBM.  Per the provisions
of the purchase agreement with IBM, the company will also pay future royalties
based on specified sales levels.  There is no minimum royalty payment required;
however, $3,000 must be paid by May 26, 2000 to retain exclusive rights to the
technology.

      The Consolidated Statement of Income includes "Special charges" for
fiscal 1994 of $(42) pretax.  This credit represents the reversal of charges no
longer necessary for which a provision was recorded in 1993.

      The company recorded special charges of $1,046 pretax in fiscal 1993.
The special charges are comprised of $1,196 for estimated severance and other
related benefits resulting from the workforce reduction which took place during
the fourth quarter of 1993.  This amount was reduced by $150 relating to the
adjustment of a previously recorded accrual, resulting in a net charge of
$1,046.

     The company has a $25,000 debt facility ($5,951 outstanding at September
30, 1995) that expires May 31, 1998, which provides unsecured, multi-currency
revolving credit at various interest rates based on U.S. prime, LIBOR or FIBOR.
Commitment fees of 1/4% are required on the unused portion of the first $15,000
of the revolving credit facility and of 1/8% on the remaining $10,000 of the
facility.

      At September 30, 1995, the company had total unused lines of credit with
domestic and foreign banks aggregating $25,588, including short-term and
long-term lines of credit of $6,539 and $19,049, respectively.  Under certain
long-term debt agreements, the company is required to comply with various
financial ratios and covenants.  Principal payments on long-term debt during
the next five years are scheduled as follows: 1996-$71; 1997-$69; 1998-$5,973;
1999-$0; 2000-$0.
<PAGE>   14
      The LIBOR interest rate was 5.875 percent and 5.0569 percent at September
30, 1995 and 1994, respectively.

      During 1995, the company entered into two interest rate swap agreements
with commercial banks to effectively fix its long-term interest rates at under
seven percent for $6,000 of variable rate debt.  The first agreement
effectively fixes the interest rate on a notional $3,000 of variable LIBOR rate
debt at 6.84 percent, and expires June 17, 2002.  The second agreement
effectively fixes the interest rate on another notional $3,000 of variable
LIBOR rate debt at 6.915 percent, and expires September 18, 2005.  The interest
differentials to be paid or received on the notional amounts of the swaps are
recognized over the lives of the agreements.  At current interest rates, the
swaps require the company to make payments to the bank.  The fair value of the
swaps was insignificant at September 30, 1995.

NOTE D - FOREIGN CURRENCY

      The functional currency for the company's foreign subsidiaries is the
applicable local currency.  Income and expenses are translated into U.S.
dollars at average exchange rates for the period.  Assets and liabilities are
translated at the rates in effect at the end of the period.  Translation gains
and losses are recognized in the cumulative translation component of
shareholders' equity.

      Certain transactions of the company and its foreign subsidiaries are
denominated in currencies other than the functional currency.  The Consolidated
Statement of Income includes foreign exchange gains (losses) from such foreign
exchange transactions of $(22), $78 and $(109) for 1995, 1994 and 1993,
respectively.

      At September 30, 1995, the company had obligations under forward exchange
contracts to sell 3,700,000 Deutsche marks, 360,000 British pounds, 5,100,000
French francs and 650,000,000 Italian lira at various dates through January
1996.  The foreign exchange contracts' amounts of $4,600 had a fair value of
approximately $4,518 at September 30, 1995.

      The company has purchased and written currency option contracts with a
commercial bank that effectively provide minimum and maximum exchange rates
that the company would receive for anticipated foreign currency denominated
sales.  Under the terms of the options, the company has the right to deliver
4,500,000 Deutsche marks at a rate of 1.50 per U.S. dollar and the obligation,
if called, to deliver 4,018,000 Deutsche marks at a rate of 1.34 per U.S.
dollar.  The
<PAGE>   16
options expire in equal amounts in February, March and April, 1996.  The
options had no effect on net income in fiscal 1995, and gains and losses on the
options, if any, are recorded as incurred.

NOTE E - EMPLOYEE BENEFIT PLANS

         The company has non-contributory defined benefit pension plans
covering approximately three-fourths of its employees in the United States and
certain non-U.S. employees.  Pension benefits are based upon the employee's
length of service and a percentage of compensation above certain base levels.
Pension expense for these plans is shown below:

      The "Projected Unit Credit" Actuarial Cost Method is used to determine
the company's annual expense.

      For the United States plan, the company uses the "Entry Age Normal"
Actuarial Cost Method to determine its annual funding requirements.  This
actuarial method currently results in funding amounts significantly greater
than the amounts expensed.  United States plan assets are invested primarily in
common stocks and fixed-income securities.

      There are no requirements for the company to fund the non-U.S. pension
plan.  Non-U.S. plan assets represent employee contributions and are invested
in a direct insurance contract payable to the individual participants.

      In addition to the defined benefit pension plan, the company also
maintains a retirement plan for substantially all of its employees in the
United States under Section 401(k) of the Internal Revenue Code.  The company
may, at its discretion, make contributions to the 401(k) plan.  Expense for
this retirement plan amounted to $539, $324 and $244 in 1995, 1994 and 1993,
respectively.
<PAGE>   19
      The company also has unfunded supplemental executive retirement plans
(SERP) for certain key officers which includes retirement, death and disability
benefits.  Expense for these benefits was $85 for 1995, $165 for 1994, and $200
for 1993.  During the third quarter of 1994 and in connection with the
retirement of its former president, the company settled a portion of its SERP
obligation through a lump-sum distribution of $1,236, resulting in a net charge
to earnings of $343.  Liabilities of $355 and $270 were accrued in the "Other
long-term liabilities" caption on the company's Consolidated Balance Sheet to
meet all SERP obligations at September 30, 1995 and 1994, respectively.

NOTE F - STOCK PLANS

      The company has employee stock options outstanding under two plans and
directors' stock options outstanding under one plan.  All incentive options
have been granted at or above fair market value at the date of grant.  The
company also has an employee stock purchase plan.  All share and per share
amounts have been adjusted to reflect the two-for-one stock split on a
retroactive basis.

Employee Stock Option Plans:
- ---------------------------

      Under the 1984 Stock Option Plan and the 1992 Stock Incentive Plan,
675,000 and 700,000 of the company's Common Shares, respectively, were reserved
for the granting of options to officers and other key employees.  After
February 11, 1994, no new grants could be issued from the 1984 Stock Option
Plan. The Compensation and Human Resources Committee administers the plans with
incentive stock options granted at not less than fair market price at the date
of the grant for a period not to exceed ten years from the grant date.  The
option price under a nonqualified stock option is determined by the Committee
on the date the option is granted.  The 1992 Stock Incentive Plan also provides
for restricted stock awards and stock appreciation rights.  This plan will
expire on February 8, 2002.  All options outstanding at the time of termination
of either plan shall continue in full force and effect in accordance with their
terms.

1992 Directors' Stock Option Plan:
- ---------------------------------

         The 1992 Directors' Stock Option Plan provides for the issuance of
60,000 of the company's Common Shares to nonemployee Directors.  Under the
terms of the plan, each non-employee Director is automatically granted an
option to purchase 600 Common Shares at the close of each annual shareholders'
meeting.  The option price shall be the fair market value of a Common Share on
the date of grant.  The option is exercisable six months and one day after the
date of grant and will expire after ten years.  The plan provides for the
granting of stock options through December 7, 2002.  During fiscal years 1995,
1994 and 1993, 4,200, 4,800 and 3,600 options were granted at option prices of
$5.19, $5.00 and $6.19, respectively.  During 1995, 1,800 options were
exercised at prices ranging from $5.00 to $7.50.  As of September 30, 1995 and
1994, 14,400 and 12,000 shares were exercisable, respectively. Options
available for future grants were 43,800 and 48,000 at September 30, 1995 and
1994, respectively.

1993 Employee Stock Purchase Plan:
- ---------------------------------

On February 5, 1994, the company's shareholders approved the 1993 Employee      
Stock Purchase and Dividend Reinvestment Plan.  The Plan offers eligible
employees the opportunity to acquire the company's Common Shares at a discount
and without costs.  Eligible employees can only participate in the plan on a
year-to-year basis, must enroll prior to the commencement of each plan year and
must authorize monthly payroll deductions.  The purchase price of the Common
Shares is 85 percent of the lower market price at the beginning or ending of
the plan year, which is on a calendar year basis.  A total of 250,000 Common
Shares are available for purchase under the plan.  Total shares can be
increased with shareholder approval or the plan can be terminated when the
250,000 shares are fully subscribed.  During 1995, 40,050 shares were issued
under the plan at a price of $4.14 per share.

NOTE G - INCOME TAXES

      The Company adopted Statement of Financial Accounting Standards No. 109,
"Accounting for Income Taxes," (FAS 109) effective October 1, 1992.  The
adoption of FAS 109 changes the Company's method of accounting for income taxes
from the deferred method (APB 11) to an asset and liability approach.  The
asset and liability approach requires the recognition of deferred tax assets
and liabilities for the expected future tax consequences of temporary
differences between the financial reporting amounts and the tax bases of assets
and liabilities.

      The cumulative effect of adopting FAS 109 as of October 1, 1992 was to
increase net income for fiscal year 1993 by $1,447, or $.21 per share.

      For financial reporting purposes, income (loss) before income taxes and
cumulative effect of accounting change includes the following components:

NOTE H - STOCK AND RELATED ACCOUNTS

         On November 6, 1995, the company's board of directors approved a
two-for-one split of the company's Common Shares and Class B Common Shares.
The split was effected in the form of a stock dividend payable on December 11,
1995, to shareholders of record on November 27, 1995.  All per share amounts
have been adjusted to reflect the stock split on a retroactive basis.

      The Class B Common Shares have ten times the voting power of the Common
Shares but are entitled to cash dividends of no more than 80% of the cash
dividends on the Common Shares.  Holders of Common Shares, voting as a class,
elect one-fourth of the company's board of directors and participate with
holders of Class B Common Shares in electing the balance of the directors and
in voting on all other corporate matters requiring shareholder approval.
Additional Class B Common Shares may be issued only to holders of such Shares
for stock dividends or stock splits.  These Shares are convertible at any time
to Common Shares on a one-for-one basis.  Following is an analysis of changes
in stock and related accounts:

Report of Independent Accountants
- ---------------------------------

To the Board of Directors and Shareholders of
Keithley Instruments, Inc.


         In our opinion, the accompanying consolidated balance sheet and the
related consolidated statements of income, of earnings reinvested in the
business and of cash flows present fairly, in all material respects, the
financial position of Keithley Instruments, Inc. and its subsidiaries at
September 30, 1995 and 1994, and the results of their operations and their cash
flows for each of the three years in the period ended September 30, 1995, in
conformity with generally accepted accounting principles.  These financial
statements are the responsibility of the company's management; our
responsibility is to express an opinion on these financial statements based on
our audits.  We conducted our audits of these statements in accordance with
generally accepted auditing standards which require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement.  An audit includes examining, on a test
basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement
presentation.  We believe that our audits provide a reasonable basis for the
opinion expressed above.

         As discussed in Notes A and G to the consolidated financial
statements, in 1993 the company adopted Statement of Financial Accounting
Standard No. 109, "Accounting for Income Taxes," effective as of October 1,
1992.

Statement of Management Responsibility
- --------- -- ---------- --------------

      The consolidated financial statements of Keithley Instruments, Inc. were
prepared by management and, accordingly, management is responsible for their
accuracy and objectivity.  The company utilizes accounting policies which are,
in the judgment of management, the most appropriate for the company's
circumstances.  Certain estimates and judgments are required in the preparation
of financial statements.  The financial information included in this Annual
Report has been prepared using management's best estimates, which were based
upon appropriate research and investigation.

      The company maintains internal accounting control systems that are
designed to detect and correct material misstatements of financial information.
These systems are regularly modified in response to the company's changing
business conditions.  Additionally, our independent accountants, Price
Waterhouse LLP, obtain a sufficient understanding of the internal control
structure in order to plan and complete the annual audit of the company's
financial statements.

      The Audit Committee of the Board of Directors, which consists of three
directors otherwise independent of the company, serves an oversight role in
reviewing the internal control monitoring process.  The Committee regularly
meets with and has direct access to Price Waterhouse LLP.

      Management acknowledges its responsibility to provide financial
information (both audited and unaudited) that is representative of the
company's operations and financial position, prepared on a consistent basis and
relevant for a meaningful appraisal of the company.
