Default Re: the pressure inside the aneroid wafer

Everything that I have read says the aneroid wafers are "partially evacuated"

However, sources aside it doesn't matter what the pressure inside them is. As long as the entire mechanism is calibrated correctly to sense the change in pressure then it will work no matter what the pressure on the inside is.
