Hi everyone.
I have a several decades old analog multimeter, which works fine except that the needle stops at slightly different position if the movement goes up, than if it goes down.
As an example. If I probe 10 volts DC (12 V scale), the meter stops at aprox 9 V.
If I change to 3 V scale, obviously the needle goes all the way up (input voltage is 10 V DC all the time).
If I quickly go back to 12 V scale, the needle now stops at 11 V.
If the needle moves up, it stops at a lower position.
If the needle moves down, it stops at a higher position.
Of course, I checked the circuit, voltage divider, etc. and all seems to be fine.
Is this a symptom of a defective panel? Anything I could test or do to solve it?
Thanks in advance for any tip.
