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 multimeter’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 multimeter’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 complete self-test.
• Perform only the performance verification tests indicated with the
letter
Q.
If the multimeter 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 multimeter. 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 with the next calibration interval.
If the multimeter fails performance verification, adjustment or repair
is required.
ALL configurations shown assume that the multimeter starts from its
power-on or remote reset state.
