[Boatanchors] DE-MAGNETIZING A METER

[Gary Schafer]

I doubt that it is a magnetization problem. It may have gotten zapped one
time and distorted the return springs. Or someone may have needed a zero
center meter and adjusted the springs. 

There are two springs. One is usually adjusted with the zero adjust on the
front. The other is the same but you have to take the meter out of the case
to adjust it. It will be like the front one but located at the back end of
the movement. Sometimes they are easy to adjust and sometimes a pain.
