I have seen several people do this; and FWIW I believe I've lost a few brain cells watching them:
At the analyzing station, with the whip & the O2 analyzer connected, and the tank valve open -- they're rocking the tank back & forth as if it's some type of cocktail. I have went out of my way to ask them "what are you doing?" and I always get the same response...."blending the gas so I get an accurate reading"
My basic knowledge of of physics tells me that a compressed gas cylinder, which is *UNDER PRESSURE* should not be affected by rocking the cylinder back-and-forth. It has bothered me enough to research the weight of oxygen vs. the weight of nitrogen. Even still, the difference appears to be negligible.....and this is assuming the gas is NOT under pressure.
Idk....I call bullsh*t
