Those clamps matter which side is used for 10×, and in this video the wrong side is used. There's one wire of the other polarity on the side he measured. That's why 10× is printed on the other side. Some splitters have markings indicating not to use that side. The inaccuracy in measuring the 10× come from the return wire being in such close proximity as it's essentially a transformer.
Hello, I was hoping you may have some insight of the accuracy differences of different ac line splitters. I have read reviews where some people say the 10x and 1x are off on some models when in theory they should be the same reading but just need a decimal place shift for the 10x vs 1x. Any thoughts on which models may be more accurate ?
@charles Lane27 No, they don’t. Usually a large amp draw receptacle like that would be on its own dedicated circuit. To test the current draw on that circuit, you have to open up the panel box and test the conductor coming from the breaker.
charles Lane27 That’d be great! You could make a pretty rough one from 2 cord ends and a short length of wire. Just strip the outer jacket off of the wire to expose the conductors inside.
Another new knowledge for today, thanks ! I am intended to create myself a simple line splitter, but then you mention the commercial line spliter has a 10x wire loops to increase accuracy on clamp measurement. That is new knowledge for me! Wonder how 10x loops can improve the precision..is it because the magnetif field increased? Also, does the loop is intended to loop close/nearwith their other line wire?
I don’t believe it has anything to do with the proximity to the other line. Like a solenoid or transformer, the more loops the greater the magnetic field.
