Hello We have one of these light meters and it is out of spec. I see there is 1 adjustment pot on the side of the unit which doesn't seem to move much so I'm thinking that's a zero adjustment pot? I took the case off and cannot see any more pots for adjustment on the back of the board, is there a button pressing procedure that can put this into a calibration mode? I have zeroed the light meter with the cap on before using it as recommended in the manual and that has changed nothing. Any suggestions as to how I can adjust this further? Regards Joel H
