Hey guys, I bought one of ur6qw meters and here is what happens to it. I connected it to my 7610 and followed thee instructions on tube to set it up. I plugged it in to the 7610 and applied 12VDC to power the meter. Turned it on and it lite up OK, but then crashes. Does this every time. Stays on a few seconds then turns itself OFF. What am I doing wrong or do I have a bad meter?
