Performance Verification Tests
Keysight M9182A/M9183A Calibration and Verification Procedure

Quick Performance Check
The quick performance check is a combination of internal self–test and an
abbreviated performance test (specified by the letter Q in the performance
verification tests). This test provides a simple method to achieve high confidence
in the instrument’s ability to functionally operate and meet specifications. These
tests represent the absolute minimum set of performance checks recommended
following any service activity. Auditing the instrument’s performance for the quick
check points (designated by a Q) verifies performance for “normal” accuracy drift
mechanisms. This test does not check for abnormal component failures.
To perform the quick performance check, do the following:
– Perform a self-test from the Tools menu on the Soft Front Panel.
– Perform the performance verification tests indicated with the letter Q.
If the DMM fails the quick performance check, adjustment or repair is required.
Performance Verification Tests
The performance verification tests are recommended as acceptance tests when
you first receive the instrument. The acceptance test results should be compared
against the 90 day test limits. You should use the 24–hour test limits only for
verification within 24 hours after performing the adjustment procedure. After
acceptance, you should repeat the performance verification tests at every
calibration interval.
If the instrument fails performance verification, adjustment or repair is required.
Adjustment is recommended at every calibration interval. If adjustment is not
made, you must establish a ‘guard band’, using no more than 80% of the
specifications, as the verification limits.
