I bought a Triplett 630 on eBay that has a problem with its needle swinging even with the most gentle movement. When you handle the meter the needle swings back and forth and takes a while to settle down. Any suggestion on what is causing the needle to swing so freely? Can it be be adjusted? Appreciate any help.

repairing clocks but have no experience of doing the same to meters. In
the end I'll probably have to find a replacement but it would be nice
to try & get the original meter working again.
