Default Re: Quick-and-dirty testgear: mains voltage monitor.

I had some of these voltmeters delivered yesterday. One seems to work as described in #1. It works from 30V up using my Variac.

I want to add one to my Variac output which gives sine wave but how would it react to a dimmer reduced supply? Would the funny waveform overdrive the works?
