When you had the cover off, on the gears that connect the geared wheel on the lever to the gear on the potentiometer have black marks on them which should align when the handle is in the zero position. If they don't, you will never get a less than 1 volt reading on the screen, and may have problems reversing locos with electronic reverse units.
