Has anybody done any bench testing?
I'm sure a refrigerator/freezer would simulate anything you would want to know about cold weather on the altimeter itself or your batteries.
Now, I've never actually "seen" a dual deploy altimeter, but I suspect they are triggered at apogee and set main altitudes via some type of membrane transducer.
Should a VERY controlled air pressure simulation/accent/decent be intoduced onto said transducer via some type of vacuum source(ultra controlled shop vac or valving?) You should be able to predict your "chilled" altimeter or batteries performance.
Don't even THINK ABOUT controlled shop vaccing your expensive altimeter until you hear some more experienced opinions than mine. I'd hate to see some one "Lawn Darting" their rocket because their altimeter was trashed by a vacuum cleaner or my far fetched ideas for an experiment.
