Using the Filter Function for DC measurements
Turn on the Filter Function when measuring DC voltage and/or current from a
mixed signal (AC+DC components) in the DC voltage measurement mode. See
"Enabling the filter"
The Filter Function blocks and attenuates AC signals to help you read the DC
measurement from a mixed signal. For instance, a DC offset with an AC voltage
signal presence (for example, AC 100 V/220 V applied to the 3 V range).
