CSA 803C Service Manual 4Ć1
Performance VerificationThissection contains procedures to check electrical specifications and
examine measurement limits listed in Table4Ć1. Use these procedures to
check the CSA 803C following repair,or to verify that the CSA 803C meets
specifications.To functionally test the CSA 803C, simply perform the proceĆ
dures which have a yes" indication in the FunctionalTests column listed in
Table4Ć1. The Specifications or Measurement Limits are given at the beginĆ
ning of each procedure. Adjustment procedures are included in the
section. Refer to the
for more information about specifications and CSA 803C operation.
The Setup in each procedure provides information concerning test equipĆ
ment setup or interconnection. Refer to Table4Ć2 for more information
concerning test equipment used in the setups.
Most PerformanceVerification and Adjustment procedures can be run in any
order.However, the Sampling Head Calibration must always precede other
procedures which use an operational sampling head (i.e., does not apply to
procedures using the Calibration Head). Also, if different sampling heads are
used, then sampling head calibration is required for each additional samĆ
pling head.
