I got a free voltage indicator (which came with an MFT) which has stopped working. It has a self test function which lights up all the LEDs and when I test it with a DC source it works but when I test it on an AC source there is only a barely perceptible flicker (for a 50th of a sec at a guess). I was just wondering if anyone else has one that has developed this dangerous fault. Also I was wondering if a proving unit would have shown this fault i.e. do they have an AC output or do they only test with DC?
