Filter Function
The instrument will perform measurements after synchronizing to the cycle of the input signal.
Consequently, the frequency of the input signal can be measured properly. The filter, at a cut-
off frequency of 300Hz, will only be applied to the frequency measurement circuit and will
remove noise from distorted and inverted waves, etc.. This allows the frequency to be measured
correctly which improves the accuracy of each measurement value. The filter will not be applied
to the voltage and current circuit. The initial value is OFF.
Note
The filter setting cannot be changed while integration is being carried out.
