Performance Verification Tests
Use the performance verification tests to verify the
measurement performance of the instrument. The
performance verification tests use the instrument's
specifications listed in the U1231A/U1232A/U1233A User's
Guide (available for download at
www.agilent.com/find/hhTechLib).
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 multimeter fails the performance verification tests,
adjustment or repair is required.
Ensure that you have read the “Test Considerations” on page 7 before
running the performance verification tests.
