So I could hook up a new meter up a battery and put it in the oven

To do it correctly you should put it in the oven at around 175F for
an hour, then immediately transfer it to your freezer for an hour.
Repeat 12 times. This is commonly called burn-in or ESS,
environmental stress screening. Do not do this with any equipment
that has an LCD display or a battery. They don't like heat. You would
have to power it with long wires.

The appropriate "burn-in" procedure will vary considerably, depending
the device and it's intended use. For "consumer" devices that aren't
critical to flight safety (like a voltmeter), don't waste your time even
thinking about it: buy and try it, and if it fails, ask for another one
or your money back. If it is critical to flight safety, buy one that's
intended for critical use (it will cost a lot more), and have a back-up
plan for if/when it fails.
