I have a cheapish multimeter I bought about ten years ago, which I have recalibrated recently.(this is how I did it) but I'm getting phantom readings on the highest resistance ranges (2M and 20M) and low readings on the 200K range. It looks as though something is shunting the input, but don't know much about how a DMM measures resistance so this is just a guess. I tried cleaning the switch, which made a bit of difference, but still have the fault.
Anybody have any suggestions as to what I should be looking for?
TIA
