Frequency Filter
Thisfilterisonlyappliedtothefrequencymeasurementcircuit.Thecutofffrequencyis500Hz.
Becausethisinstrumentmakesmeasurementsinsyncwiththeinputsignal,thefrequencyoftheinput
signal must be measured correctly. The default setting is oFF.
• on:ThefrequencyfilterisenabledandtheFREQindicatorilluminates.
• oFF:Thefrequencyfilterisdisabled.TheFREQindicatorturnsoff.
Even if you enable the frequency filter, the measured voltage and current values will include harmonic
components.
Note
You cannot enable or disable input filters between the time when integration is started and the time when it is
stopped and reset.
