AC VOLTS Gain Verification Test
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, set the AC VOLTS function and the 3 Hz input filter. With
the slow filter selected, each measurement takes 7 seconds to complete.
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.)

[b] For this test, isolate the calibrator’s output from earth ground.
[c] Some calibrators may have difficulty driving the internal DMM and cable load at this V-Hz output. Use short, low
capacitance cable to reduce calibration loading. Verification can be performed at >195 Vrms. New test limits can
be computed from the accuracy specification shown in Chapter 1 for the actual test conditions used.
