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.

brother check it to a good mechanic..

Update: Found out that the meter is open.

Hmm... Did the ad say "untested"? I am really tired of receiving items that are either dead or some unnamed defect.
