You might want to open that meter and see if there's a shunt inside. Frankly
, I don't remember seeing any meters with 100 or 500 ma. basic movements. ,
but I have seen some with shunts inside and scales for the higher current
levels!!!! .02 cents worth!!

came from an old PSU I bought off a ham who was giving up and he had used a
500mA meter to measure the HT voltage, so I guessed my 100mA one was ok! I
should have realised from all the dodgy construction practices I found when
I dismantled his psu that I shouldn't base anything on his judgement!!! We
live and learn!
