I haven't used it in a while, I've been using a leader LDM-170 but feel more confident in triusting the 334A. First problem is that you can't "Set" anything unless you have an extremely high voltage signal going in @1VAC then you can fake go through all the steps. second, the auto function works but I'm not sure if it's 100% or not. I'm in Knoxville Tn.
