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

DC voltage and true RMS voltage are equivalent.
DC meters read the average, DC value of a wave.
That really should be qualified.

The way I understnd it is that the RMS voltage produces the same ammount
of heat in a resistor as a DC voltage will.
However RMS voltage could be a high peak value that will damage solid
state devices. The meter could show 5 volts, peaks could be 50 volts.
Again DC meters could read many different values depending on the meter
and wave form.
** What I wrote was accurate.
Strange how so many are baffled by such simple stuff.
