A recent campsite revealed an open area near our dining pedestal. The electrician came to check and found nothing wrong with the connections other than a low ground fault. He checked the other 5 sockets in our circuit which also showed a low ground fault but couldn't find the source. He asked to borrow my surge protector to help diagnose the problem as it turned out to be more sensitive than his network analyzer. With that he finally found a vacant land where the main line fed our circuit. I was very impressed and have complete confidence in the sensitivity of this instrument and how well it performs.
