  • I’m curious how well a KAW measures True Power. Has anyone measured (with a multimeter) voltage (V) and current (I) of various devices, multiplied the measured V and I, and compared the result to what a KAW indicates? If there is a large difference for a motor load, and a small difference for a lamp or toaster, then the KAW is reporting True Power.

No public wish lists :(
