Performance Verification

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 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 (see page 23).
– Perform only the performance verification tests indicated with the letter Q.
