I checked it that way and the Amps are within .1 of what 1/2 of my meters show.  And I put the clamp on meter on the DC input side. The load there matches what the display shows + - 1% on the low end load. Like I said, the meters I have must be figuring the Wattage based on the power factor also.

I did calibrate the WiFi unit. Now it is within 1 Volt at 240V and .1 Amp at the low end.  So on the low end it is off by less than 2 Watts high. Middle range with an ~1800 Watt load, it is off about 40 Watts low.  Voltage was dead on, current was still within .1 ( .2 on the 120V ) Amp.

Does it still read not-quite-right numbers with different power factor loads?

I didn't think to check what the PF was on the 1800 Watt load.  Will check that tomorrow.
