In this video I go over the basic operation of a non-contact voltage tester.
I feature a couple of different styles of non-contact testers. Some are built into a normal voltage meter and some are hand-held purpose built testers. I do demonstrate several Klein branded tools but I am not sponsored by them. It's just a coincidence.
