AC voltage and calibration

CT clamps measure apparent power

I hope I get the power factor rather stable for the loads I want to measure, but we'll see.

With only a few callibration points for like 2A and 5A I found that the readings where too far off with smaller loads like a light bulb.

That's what I was afraid to see. Good to know I need to find smaller resistive loads as well. My current lowest is around 0.65A but some loads I want to measure get down to 0.1A.

Did all the testing at once by putting all 16 CT's on 1 wire and took note of all the values for each test and put them in.

Wouldn't it be better to measure on actual wires in the walls? I believe the readings may be influenced by plenty of wires around in my fuse box.
