Performance Tests and Calibration 1
Performance Verification Tests
34450A Service Guide 9
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 one year test limits. 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.
Zero offset verification
This test is used to check the zero offset performance of the instrument.
Verification checks are only performed for those functions and ranges
with unique offset calibration constants. Measurements are checked for
each function and range as described in the procedure on the next page.
NOTE
Ensure that you have read the “Test Considerations” on page 5 before running the
performance verification tests.
