Performance Verification Tests Overview
Performance verification tests is an extensive set of tests that are recommended
as an acceptance test when you first receive the instrument.
Use the performance verification test to verify the measurement performance of
the instrument. The performance verification test uses the instrument’s
specifications listed in Chapter 6, “Characteristics and Specifications”.
Performance verification tests
The performance verification test is recommended as acceptance tests when you
first received 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.
Contact your local Keysight Service Center for details.
This test checks the full-scale reading accuracy of the instrument.
