Re: Quick-and-dirty testgear: mains voltage monitor.
I have done some measurements on the little mains indicators.
The dimmer was driving a small bulb.
The DM25 was set to a specific value, either with a Variac or a dimmer and the indicator noted.
DM25 meter (RS) Variac Indicator Dimmer Indicator
50 62 40
100 100 110
150 152 156
200 202 210
236 238 236
It looks as if the meters are measuring in the same way, presumably mean voltage.
