Test with a new battery
wandows:
I tested with a new battery but the problem remains!
Fungus:
Take it apart, clean the rotary switch contacts and PCB.

Are you sure nothing bad happened the last time you used it? What did you measure with it?
wandows:
The batteries leaked a little and I took the opportunity to disassemble it and clean it as you mentioned.

Before that, no wrong measurements were taken (this Aneng is not always used).

In other words: Something bad did happen. Why didn't you mention that?

The PCB could be contaminated, the rot could even have got inside a component which would be difficult to fix. You could try scrubbing with IPA and a brush but at this price you're probably better off getting a new one.

And don't use any more alkalines in stuff that goes long unused for long periods.
