Hmmmmmmm ? I wasnt aware of a GFP function, Yes the Ideal tester has a coil in it, I figured some type of inductive loading, or kickback. After i reset it I had the carpenter plug in his electric planer and it worked fine and then told him to turn the switch on and then plug it in and it worked fine again, so maybe that's it, other than that it worked great. Maybe now I should read the instructions ?? Ha ha ha........ You know what they say if all else fails read the instructions.
