Oh, be sure to calibrate your Hickok. I forget where I saw it, but there is a site out there that tells you step by step how to calibrate your tester. I'll see if I can't find that link again.
Yeah, that'd be great. I didn't know it was an easy thing to do, but upon thinking about it, I don't see why it wouldn't be straight forward enough.
I have a 534 also, I think that is the right number, but it arrived and wasn't working. So it needs to get fixed, but the site Gary pointed to had the schematic for it as well. I was going to send it out to get fixed, but I may try to trouble shoot the PSU first. I don't think I want to trouble shoot the rat's nest, I'll pay someone to make it their problem.
