Let's suppose the meter WAS connected properly......then what ? Since this has a dc-dc converter, it's possible the output was pulsating, rather than smooth DC. In which case the meter might be attempting to measure peak or RMS current. In that case, the higher-than-expected reading might actually be correct. All kinds of weird things happen in switched circuits, that's why your oscilloscope will be the most important tool you have.
===================================================================================================== BTW, I just discovered two back-to-back mistakes on my own that have had me running in circles for months now. Two PCB sets (6-tube NIMO clock) . Both board sets "working", except board-set #1 was heating more than the other, and board-set #2 would randomly fail after several hours where the A/D converter "hung". and could not be reset despite all sorts of diagnose-and-repair software I had to write. Board #1 had a damaged NMOS transistor in the HV section, and board #2 had a weak solder joint that eventually failed. I did all of the "shake/wiggle/jiggle" testing more than a year ago and never saw anything go wrong. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
