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 U1190A Series User's Guide (available for download at
www.keysight.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 clamp meter fails the performance verification tests, adjustment or repair is
required.
Ensure that you have read the
NOTE
the performance verification tests.
