John,
Take a small SOFT rag and wet it, squeeze most water out...then run it
across the meter movement a few times...
I think it will help with any 'static effects' which is what I have had
happen.
Yes, that is a delicate opertion to straghten the meter pointer, but
you can do it.
Maybe get someone with a very steady hand if you think yours is not
good enough.

Ron,
Thanks for your input. I'm a little afraid to try bending the needle.
It's going to take a steady hand. I wonder if the problem develops
because of some residual or stray magnetism. If that were the case
possibly a degaussing device like used to demagnetize tape heads would
resolve the problem. I believe I have one of those devices around here
some place left over from my days of servicing tape decks.
If I can dig it up it may be worth a try.

John,
I have a meter here too that is the same way. It appears that the
meter movement is made of a disc of magnetized? material inside of a
coil. I was going to carefully bend the needle, but I happened upon
"new" one. It's been some time, but I was going to approach as
follows. Put a close fitting brass tube from the model airplane shop
over most of the needle. With a very fine pointed pliers hold the base
of the needle (above the movement bearing area). Now very slowly bend
the needle in the direction needed.
BTW this was the meter that left me with a small piece of plastic in my
cornea. Just had my eyes exam this week, and doc tells me I am a very
lucky.

My T-4XB meter movement is off scale to the left of the zero mark. I
have removed the meter and to my surprise there doesn't appear to be
anyway to zero the needle. Any suggestion to get the needle to rest at
zero would be appreciated.
Thanks,
