Measurement Setups
Voltmeter
To ensure that the values read by the voltmeter during both the verification procedure and the
calibration procedure are not affected by the instantaneous measurement of the ac peaks of the
output current ripple, make several dc measurements and average them.
If you are using a Keysight 3458A DMM, you can set up the voltmeter to do this automatically. From
the instrument’s front panel, program 100 power line cycles per measurement. Press NPLC 100
ENTER. Additionally, turn on auto-calibration (ACAL) and the autorange function (ARANGE).
