Anyone tried to use this frequency meter on an AC Frequency Drive. I know the output of the drive is Pulse Width Modulated not a sine wave. I was hoping to monitor the output frequency of the drive and SET a relay output to show less that 20Hz and more than 30Hz?

Thanks,
jerry

I realized that the correct part is Model: HB404F
