Um...Me123 Posted October 1, 2006 Report Share Posted October 1, 2006 OK So I bought this LCD panel meter to measure VDC (20Max) and I hooked a 9V battery to the power leads and it said 0.00. Great so I hook it up again 5 minutes later it didn't work and has never worked again. Bought another one finally several months later (has to be ordered) and I just hooked it up (said 0.00) and I hooked it up again (after going up the stairs) when I was about to put it into the panel to make sure I new the polarity and it didn't work!!!!!!! I can't get it to work at all now!!!! What is going on!!!! I'm really mad at this point because it's not cheap. Quote Link to comment Share on other sites More sharing options...
ante Posted October 4, 2006 Report Share Posted October 4, 2006 Hi,Some of these meters has a working voltage of 5.0V, have you checked its datasheet? You might have killed it! :o Quote Link to comment Share on other sites More sharing options...

hotwaterwizard Posted October 28, 2006 Report Share Posted October 28, 2006 Maybe it killed the battery from too much load.Did you try a new battery? Quote Link to comment Share on other sites More sharing options...
gtwms Posted December 8, 2006 Report Share Posted December 8, 2006 Most, but not all, of the digital panel meters require an independent power source from the supply that you are measuring. Quote Link to comment Share on other sites More sharing options...
