reset procedures, and performance verification tests needed after an
assembly replacement. Adjustments and performance verification tests
and the utility that resets the calibration constants and resets the
statistical data are located in the Performance Verification and
Adjustment Software.
Calibration constants are stored on most board assemblies. Several
PSA model numbers share the same board assembly, but require
different calibration constants.
After an assembly is replaced, find the assembly that has been replaced
in the left-hand column, and then perform the adjustment, test, or
configuration procedure shown in the adjustment column. After
successfully completing the necessary adjustment, test, or configuration
procedure, verify that the instrument meets specifications by running
the performance verification test or tests listed.
Refer to your user's guide for information on instrument warm-up
