I have a battery tester meter (Mallory) that came from a retail store. The
meter is magnetized and now sits center scale, instead of over to the left.
Any solutions to return it to it's normal state. I tried reverse polarity-
it goes to the left, but then returns to center.

I've seen such an effect when the transparent plastic cover of the scale
has
been wiped intensively for cleaning purposes generating electrostatic
charge.
Try to breathe on the plastik to discharge it.
