I would go a lower than 170 degrees, maybe about 120.

A light bulb placed close by will dry things without hurting it.
::Moisture in a meter can't be a good thing. You'll need to open it up so the excess moisture will escape - not a complete disassembly, just open it up a bit and leave it outside in direct sunshine on a clear & dry day. That should do the trick. Another thought - you could tape one of those "Do Not Eat" dessicant packs inside to meter to soak up residual moisture.
: Thanks for all the replies. The dessicate packs (Don't Eat), even the small ones, will not fit in the meter case. The mechanism fills the entire space. Oven will only go down to 170 degrees which I also felt was too high. Here's what I did, oven at lowest setting (170), put meter mechinism in oven, door left cocked open (door has a position), watched as temperature stabilized at about 150 degrees with door cocked, left it in there for 45 min to hour, turned off oven, closed door and am waiting for it to cool down then I will remove and reinstall and find out if it worked. May need longer? Will see and report back. By the way I left it in the oven to cool down since I felt that if I removed it immediately the faster cool down in open air may cause some condensation to accumulate. PL

As previously suggested... unless you open her up you're spinning your wheels....... in a tightly-sealed environment, heating won't magically make the moisture disappear without an outlet for egress of the vapor.... it will only vaporise what's in there and it'll recondense when cool. And... all your heating & cooling is doing nothing good for the movement.... in doing so you are only redistributing the moisture into EVERY nook & cranny. Eventually rust and oxidation is going to crap out the meter if you aren't careful.
WatchMaker, I'm sorry if I didn't state that the mechineism was removed from case and put in oven. As I said I then placed it back in unit but did not close it up and ran it with 100 watt light bulb in two sessions totaling an hour and a half. Buttoned it up today and so far it is not fogging up. Will check again tomorrow for fogging. PL

Yeah - it wasn't clear whether you had taken it out of the case. If there is room inside, perhaps you could slip a small piece of this inside the case..... http://www.action-electronics.com/bullfrog.htm
Watchmaker, that seems like a good product and I may try it. The funny thing is the other day I was thinking about my grandmother putting a shoot glass of oil in the wind-up clock (complete with pendulem) on the kitchen table. She believed it keep it oiled. I'm not too sure but you don't disagree with grandma. PL
..................................................
What was in grandma's shot glass before she came up with this little trick? Sounds like granny liked to get a little 'oiled' herself.... (only kidding - lol)
She told the kids it was oil but actually where she kept her jigger of 'grandmas little helper' handy at all times
Actually, guys, grandma use to save the shot of rum for the Christmas fruit cake. She would leave a shot glass full of rum in center and close tin, cake would not dry out and people actually ate it! PL
