The other way to calibrate it is in a 100% Nitrogen environment which is how it came shipped but I didn’t know that. So I tried creating a 100% Nitrogen environment to recalibrate it but that, turns out, is hard to do. I went to a welding supply store who sells 99.9% Nitrogen gas but the other .1% was probably air which was enough to throw off the calibration. Remember we are taking about .03% of the atmosphere.
