I am in the U.S. and was having an issue with a 220 outlet, my Fluke meters (77 & 101) both said I had 110 from neutral to either hot which is what there is suppose to be but the equipment would not work properly. I had an electrician come out and his meter (a plug in one with just lights for each voltage) showed no voltage across the neutral to hots, he found in another box that was daisy chained to this one the neutral had come loose.
My question (and one that concerns me very much) is why did my Fluke meters show 110v when they should not have? BTW I plugged mine in with electrician there and showed him it said it basically had the neutral and was OK, he just said I don't know but there was definitely no neutral hooked up to that outlet. He hooked up the loose neutral and everything worked.
Now I have used Fluke's for 30+ years and I just lost confidence in them.
Can anyone explain why it showed proper voltage with no neutral?
Thanks!
