I am using a 12 V 20 amp lamp dimmer to control some LED lighting.
While my two DVM's show nearly equal input voltage to the dimmer, they
both read separate voltages on the output side. One is reading 9 V
and the other 4 V. I am trying to determine wattage output at various
dimmer settings. Why the different in voltage readings on two
different DVM's and how to remedy?

**Measure the output of the dimmer with a CRO and it may make a lot more
sense.

You talking a scope here or something else? If a scope,
unfortunately, I don't own one.

Its probably a great idea if these questions were actually posed to the DMM or oscilloscope mfg'erers, too.
