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.Â* One is reading
9 V and the other 4 V.Â* I am trying to determine wattage output at
various dimmer settings.Â* Why the different in voltage readings on
two different DVM's and how to remedy?

more sense.

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


**Well don't waste your time until you acquire one. In this application,
most meters are almost useless.
