I was taught 3% deviation from expected at 1.0
Which is going to get bigger once you get to ppO2 1.2-1.3
Your 8% deviation at 1.0 will be 20% larger at 1.2 (0.096 or almost 10%) A 10% deviation means your 1.2 is really 1.3. That is too much.
PS your cell quality is awful. You need a better supplier
So you think that it's the cells? I'm really at a loss here.
These are JJ Vandagraph cells, straight from the US JJ distributor in two cases (two different US distributors over the years). At one point I used AI cells from DiveGear Express, but they were very wonky and I replaced them. So this is why I was wondering how accurate the auto-calibrate system is in terms of getting a good 1.0 flush over the cells, since other units don't rely on that. Could it be that your stricter deviation requirements require a better calibration sequence?
Any suggestions? This is not a one off. I have a lot of data over the years.
Thanks for the help...
