Hi Reji.

Meter movements are called D'Arsonval movements. Many have jewels in them(typically two),
a are EXTREMELY DELICATE. They are built the same way as mechanical watches. In essence,
they are mechanical watch movements.

So, unfortunately, once damaged they may be repaired, but they are NEVER the same as
before. I would recommend replacing the meter if you can find one, or just throwing the
whole thing out - it sounds like it is kaput. Once damaged, the accuracy is destroyed.

I hope this helps.

Harve.
