Other than the spot appearing when I plug it in, I'm not sure how to test it - if you have any ideas then shoot me an email and I'll give it a try. Zero adjust knob works fine - it is very sensitive - just as I remember them. No damage anywhere. Any questions just ask me. I'll ship double boxed USPS Priority. No reserve auction.
