I just received a lightly used Fluke 376 Clamp meter with iFlex cable. I tested it out on my toaster oven. I read 9.3A. I then tried it with the iFlex cable and read 8.7A. So I went back and tried it with the regular clamp and got 8.7A. A few times switching back and forth between regular clamp and iFlex cable and I figured out that with the regular clamp, I will read 8.7A or 9.3A depending on which direction I clamp the cable. It's very repeatable. I did it 5 or 6 times in a row...8.7A, flip it over, 9.3A, flip it over again, 8.7A.
I'm wondering if this is normal; I've never done a test like this on another clamp meter, and for all I know, they all do this. Can anybody confirm/refute this? Anybody have an explanation?
