So on a service call today I found a tripped 60A breaker. Went to the unit and started testing all the major components to ground and looking for rub outs before turning the unit on. Found compressor 1 was reading to ground but the reading would start in the 20 megaohm range and climb until reaching OL. I went and checked my meter on a separate unit and the readings would just be strictly OL with no Ohm reading at all. Has anyone else ran into this? It was making me question the accuracy of my Fieldpiece meter. Unfortunately I haven’t yet purchased a megger that would have been a more accurate reading for this situation. #teachme
