Thanks Lee but that was already tried with no effect. When I removed the plastic cover there was no change in the needle position. Warning!! Don't try to remove the metal case to gain access to the movement. You will be sorry you did, pop off the front. I removed the solder lugs to get the meter out of the transmitter, don't take the nuts off the back, desolder the wires instead.
