Because I decided to regulate 230VAC with a dimmer (or SCR chopper), I want to measure the outcome (which is very big noise!) with a voltage and current meter.
I know I am supposed to take true RMS instrument, but would analog work too?
I don't find it logic for NOT to work, because the voltmeters are actually just a non-spinning motors, which could be interpreted as: "I use dimmer to regulate speed of motor, which is in this case a voltmeter". And the same could be said for current meter.
