Performance Verification Tests
Use the performance verification tests to verify the measurement performance of
the multimeter. The performance verification tests use the multimeter’s
specifications listed in the U1241C/U1242C
datasheet
(
http://literature.cdn.keysight.com/litweb/pdf/5992-0848EN.pdf
).
The performance verification tests are recommended as acceptance tests when
you first receive the multimeter. The acceptance test results should be compared
against the 1-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
Ensure that you have read the
on page 24 before running
the performance verification tests.
