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.
Configuration: AC Volts
LF 3 HZ:SLOW (in the Advanced menu)
1 Make sure you have read “Test Considerations” on page 76.
2 Select Channel 210, select the AC Volts function and the 3 HZ filter. Before
executing each test, you must press to enable reading monitoring on the
selected channel (or use the ROUTe:MON command from the remote interface).
3 Select each range in the order shown below. Compare measurement results to
the appropriate test limits shown in the table. (Be certain to allow for
appropriate source settling.)
