What is the Filter Function of Leakage Current Clamp Meter?
QIn what situations would you use the filter function equipped with the AC Leakage Current Clamp Meter?
A low-pass filter removes unnecessary harmonic components.
With the widespread use of switching power supplies and inverter equipments, harmonic components may be superimposed on the waveform of the leakage current.
When the filter function is enabled, the frequency band is limited to approximately 180 Hz (-3 dB), which is equivalent to the frequency band of a typical electrical leakage breaker.
Using the filter function is recommended when analyzing the operation of a leakage breaker
