Item 2.           MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Comparison of Three Months Ended September 30, 1996 and September 29, 1995

     Revenues, Net.   Total revenues increased 7.7% in the three months ended
September 30, 1996 ("the 1996 period") to $11.2 million, compared to $10.4
million in the three months ended September 29, 1995 ("the 1995 period").
Revenues from the sale of products increased 2.4% to $8.1 million in the 1996
period from $7.9 million in the 1995 period.  An underlying reason for the small
increase in product revenues was the significant increase in backlog orders.
The product backlog as of September 30, 1996 increased $920,000 to $2.5 million
as compared to $1.6 million as of September 29, 1995.  Service revenues
increased 24.6% to $3.1 million in the 1996 period from $2.5 million in the 1995
period primarily as a result of the increased emphasis in maintenance contracts
and consulting services due to greater sales support.

     Cost of Revenue.   Total costs of revenues increased 14.2% to $4.6 million
in the 1996 period from $4.0 million in the 1995 period.  As a percentage of net
revenues, total cost of revenue increased from 38.6% in the 1995 period to 41.0%
in the 1996 period.  Product costs decreased 9.0% to $2.0 million in the 1996
period, down from $2.2 million in the 1995 period.  This is primarily due to a
three hundred basis point increase in the overall product gross margin
percentage, which resulted from favorable pricing resulting from the use of
blanket purchase orders.  Evidence of the favorable pricing is the reduction of
standard costs for 1996.  A reduction in the labor hours required to assemble
an item also contributed to the decrease in product costs.  Service costs
increased 42.4% to $2.6 million in the 1996 period from $1.8 million in the 1995
period.  As a percentage of service revenues, service costs increased 10.3 basis
points from 72.2% in 1995 to 82.5% in 1996.  This is due primarily to the
addition of thirteen field service reps and the increased costs associated with
the increased consulting service revenues.  Costs associated with the Company's
service business are accounted for almost entirely in cost of revenue.

     Selling, General and Administrative.    SG&A expense decreased 8.3% to $3.8
million in the 1996 period from $4.2 million in the 1995 period.  The decrease
was due primarily to favorable experiences with bad debts, health self insurance
claims and other miscellaneous expenses in comparison to the prior year.
SG&A expense, as a percentage of net revenues, decreased to 34.1% in the 1996
period from 40.1% in the 1995 period.

     Research and Development.    Research and development expenses decreased by
$115,000 or 9.8% to $1.1 million in the 1996 period from $1.2 million in the
1995 period.  As a percentage of net product revenues, research and development
expenses declined to 13.1% in the 1996 period from 14.9% in the 1995 period.  A
significant portion of the decrease in research and development is due to the
capitalization of the costs incurred to develop new products.

     Income from Operations.    Income from operations for the 1996 period
increased 66.7% to $1.7 million or 15.4% of net revenue, from $1.0 million, or
10.0% of net revenue, in the 1995 period.   Total operating expenses decreased
by 8.6%.

     Interest Expense/Income.    Interest expense decreased from approximately
$82,000 in the 1995 period to less than $1,000 in the 1996 period, primarily as
a result of the retirement of debt and borrowings under the line of credit from
the proceeds of the Company's Initial Public Offering (IPO) in August 1995.
Interest income increased 152.0% in the 1996 period to $133,000 from $53,000 in
the 1995 period due to proceeds from the IPO being invested in short-term
government securities that bear interest at approximately 5% per anum.
<PAGE>
     Income Taxes.    The Company's effective tax rate for the 1995 and 1996
periods was approximately 36%.


Comparison of Nine Months Ended September 30, 1996 and September 29, 1995

     Revenues, Net.   Total revenues increased 12.6% in the nine months ended
September 30, 1996 ("the 1996 period") to $33.2 million, compared to $29.5
million in the nine months ended September 29, 1995 ("the 1995 period").
Revenues from the sale of products increased 9.0% to $24.4 million in the 1996
period from $22.4 million in the 1995 period.  The increase in product revenues
is due primarily to the introduction of the Company's two-channel 2120 analyzer
in early 1996.  Service revenues increased 23.9% to $8.8 million in the 1996
period from $7.1 million in the 1995 period primarily as a result of an
increased emphasis in the maintenance contracts area, consulting services and
an increased number of predictive maintenance service contracts due to greater
sales support.

     Cost of Revenue.   Total costs of revenues increased 11.0% to $13.4 million
in the 1996 period from $12.1 million in the 1995 period.  As a percentage of
net revenues, total cost of revenue decreased from 41.0% in the 1995 period to
40.4% in the 1996 period.  Product costs decreased 6.7%  to $6.3 million in the
1996 period from $6.8 million in the 1995 period primarily due to favorable
pricing that resulted from the use of blanket purchase orders causing a
reduction of standard costs, decreased labor hours required in the manufacturing
process due to improved technologies, while other efficiencies and improvements
were derived from the Company's ISO 9002 processes.  Service costs increased
33.9% to $7.1 million in the 1996 period from $5.3 million in the 1995 period.
As a percentage of service revenues, service costs increased 6.0 basis points
from 74.4% in 1995 to 80.4% in 1996.  This is due primarily to the front-end
loaded cost of establishing an increased number of field service locations
through mid-year 1996, costs associated with support of our consulting
contracts, as well as a general increase in services costs associated with
higher services revenues.  Costs associated with the Company's service business
are accounted for almost entirely in cost of revenue.

     Selling, General and Administrative.    SG&A expense increased 9.6% to
$12.4 million in the 1996 period from $11.3 million in the 1995 period.  The
increase was due primarily to additional market development expenditures such
as an addition in the number of sales and administration personnel and the
higher commission expense due to increased sales, partially offset by favorable
experiences with bad debts, health self insurance claims and other miscellaneous
expenses in comparison to the prior year.  SG&A expense, as a percentage
of net revenues, decreased to 37.5% in the 1996 period from 38.4% in the 1995
period.

     Research and Development.    Research and development expenses increased by
$187,000 or 5.5% to $3.6 million in the 1996 period from $3.4 million in the
1995 period, reflecting net additions to the Company's staff in support of a
more diverse product line.  As a percentage of net product revenues, research
and development expenses declined to 14.7% in the 1996 period from 15.2% in the
1995 period.

     Income from Operations.    Income from operations for the 1996 period
increased 41.6% to $3.8 million or 11.3% of net revenue, from $2.7 million, or
9.0% of net revenue, in the 1995 period.   Total operating expenses increased by
8.7%.
<PAGE>
     Interest Expense/Income.    Interest expense decreased from $373,000 in the
1995 period to approximately $2,000 in the 1996 period, primarily as a result of
the retirement of debt and borrowings under the line of credit from the proceeds
of the Company's Initial Public Offering (IPO) in August 1995.  Interest income
increased 297.0% in the 1996 period to $385,000 from $97,000 in the 1995 period
due to proceeds from the IPO being invested in short-term government securities
that bear interest at approximately 5% per anum.

     Income Taxes.    The Company's effective tax rate for the 1995 and 1996
periods was approximately 36%.


Liquidity and Capital Resources

     Since its inception, the Company has financed its operations through a
combination of cash flow from operations, bank borrowings and equity capital.
The Company's capital requirements have arisen primarily in connection with
purchases of fixed and intangible assets, including acquisitions, and the
Company makes significant expenditures each year for research and development
and market development.

     Net cash provided by operating activities in the first nine months of 1996
increased to $3.5 million from $1.8 million in the first nine months of 1995
primarily due to an increase in net income that reflects the higher level of
business activity and a higher level of deferred revenue that is evidence of the
increased activity in the maintenance contract area.  Investing activities
primarily include additions to property, plant and equipment.

     On October 28, 1996 the Company acquired Maintenance & Diagnostics, LLC
(M&D) for approximately $7.6 million payable with a combination of cash and
stock.  The purchase price consisted of $1.48 million paid to a partial owner
for amounts owed under a line of credit agreement, $1.49 million paid to owners
of the company for their ownership interest, $2.4 million in promissory notes
that mature January 2, 1997 to owners of the company, 73,146 shares of CSI
Common Stock issued to certain owners and a related party at the time of
closing and 27,706 shares of CSI Common Stock to be issued to the owners on
January 2, 1997.  In addition to the cash paid and stock issued above, CSI
issued options to the owners of M&D valued at approximately $750,000.  M&D is a
research, service and training center which services the electric power
industry.

     The Company routinely engages in transactions in foreign countries.
Substantially all of the Company's transactions are denominated in U.S.
currency, thereby limiting the Company's exposure to fluctuations in foreign
currency exchange rates.
