Ac Voltage Amplitude Accuracy, Squarewave (Aux) - Fluke 5500A Operator's Manual

7-26. AC Voltage Amplitude Accuracy, Squarewave (AUX)

This verification test is optional. It is not necessary to guarantee the full
calibration of the instrument. However, it may be useful when
troubleshooting an instrument when other functions and/or parameters are
incorrect.
The AC Voltage Amplitude Accuracy, Squarewave (AUX) tests the amplitude accuracy
at the AUX terminals. For this test, use the Fluke 5790A, and an rms-responding meter.
For squarewaves, the measured value (in rms) should be exactly half the nominal peak-
to-peak value.
