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.

1 Make sure you have read “DMM Test Considerations” on page 42.
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.)
Input Error from Nominal
