I was successful measuring the mid point on my 12volt house battery system (2 × 6volt Batterys in series) up until yesterday. Now they are not reading accurately. 2 volts lease than actual. I have also try this on my start battery (24 volts) and this input is measuring 5 volt less than actual.

check the small fuse and make sure its 1amp and not 500Ma also reset the unit to factory default and see if this helps.


Also try a diferant board on the shut as the board maybe damaged due to some external event ???
