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?

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