Optional AC Performance Verification Tests
These tests are not intended to be performed with every calibration. They are provided as
an aid for verifying additional instrument specifications. There are no adjustments for
these tests; they are provided for performance verification only.

Make sure you have read “DMM Test Considerations" on page 55.
2 Select the AC Volts function and the 3 Hz filter.
3 Select each range in the order shown below. Provide the input voltage and frequency
indicated. Compare measurement results to the appropriate test limits shown in the
table below. (Be certain to allow for appropriate source settling.)
