Yesterday I noticed I had managed to burn the DMM fuse. Must've probably had the meter set to measure current while probing for voltage reading at some point.
After replacing the fuse, I'm getting current readings again but the magnitude is way off, like plugging the meter in series with the circuit of a 1k resistor with a 10V DC supply shows ≈ 120 mA. If I split the supply voltage in half, I'm getting then half the 'wrong' current, ≈ 60 mA.
This loss of magnitude only happens with the current measurements that pass the fuse. High current (10 A) setting still gives original correct values. I've triple checked that there's a good contact between the fuse and its holder.
What might be causing this?
