The 8962C1 frequency converter dedicated measuring instrument is equipped with 500Hz and 5kHz filters. When measuring frequency conversion motors or poor voltage signals, it can choose to filter the voltage and current signals to remove the influence of high-order harmonics.
The waveform output by a frequency converter is generally modulated. If voltage filtering is not performed, the voltage waveform will be very chaotic, with large and unstable values. After using filtering, the waveform will appear smoother and the data will be stable.

The voltage waveform output by the unfiltered frequency converter is shown in the following figure:

The voltage waveform output by the filtered frequency converter is shown in the following figure:
