6 Performance Tests and Calibration
Performance Verification Tests
Use the Performance Verification Tests to verify the
easurement performance of the instrument. The performance
verification tests use the instrument’s specifications listed in
the U1251B/U1252B Data Sheet.
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.
NOTE
Make sure you have read the “Test Considerations” on page 114 before
doing the performance verification tests.
