[R-390] Stuck Meter

[Larry H]

Hi Guido,  If you are good at working on small fragile things, then it might be worth it to try it.  I have successfully repaired a few and also broken some, so you need to be the judge. As Roy mentioned, if it's a radioacitve meter, you need to be careful not to inhale any dust from its inners or get it in your eyes.  Don't lick your fingers while working on them.  It's not difficult to work on them and be safe.  Use logical care.  Wash your hands when done.  There are a dozen manufactures, so opening them up can be easy or difficult, depending on their method of sealing.  Sometimes that's the most difficult part.  If your not sure about opening it up, post a picture here.
Regards, Larry

Merry Christmas and Happy New Years!
