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.
No dispute on that, just why a DVM might not read it right.
** Cannot possibly help but do so.
Analog ones do so by virtue of meter needle inertia.
DVMs do so by virtue of a simple LP filter at the input.
