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 as described in the preceding section.
•
Perform only the performance verification tests indicated in the
following tables with the letter
Q
.
If the instrument fails the quick performance check, adjustment or repair
is required
