That looks like something you work on power lines with. Maybe i should leave it to the pro's . I wacthed Dad do this and he had some type of meter he would use sometime as well. It was most likely something like you posted. I know he always said keep your finger's out of there or it will knock you on your As-. This is not my idea of a real good time. :laugh:
Oh, make no mistake about it.
Those voltages are lethal.
