LOW PASS FILTER (50-60 HZ) & APPLIANCE FILTER
Low Pass and Appliance filters are used to filter out high
frequency noise that affect precise measurement of the meter.
• Use Low Pass 50/60Hz filter to perform measurements on
equipment driven by Variable Frequency Drives (VFDs) or
affected by high frequency noise. Significant difference
in reading between measurement with and without low
pass filter may indicate presence of harmonics.
• Use Appliance Filter to conduct leakage current
measurements of appliances in accordance with
IEC/EN 61557-16 regulation requirements.
