Default voltage of dimmer output not reading same on two different DVM's

AHA, the keystone part of the puzzle. This blows Phil's statement out the water which is rare, there is no TRMS in DC.


** FYI:

" true RMS " = DC equivalent value for the *heating* effect on a resistance.

Repeating waveforms may have a DC offset = average DC value.

The "true RMS" value of such wave is:

sqrt ( DC ^2 + ACrms ^2 )
