In my case it is working only “50%” in the Mooshimeter beta.
The upper part saves the the value, in my meter ~9,67 ohm but only keeps subtracting it until it shows the first time overload. Than it is still printed in the ZERO field but no longer subtracted.
In the lower part it works as expected.
Hope it helps fixing the problem … If it is not a new one after 7 month.
