According to the documentation, the atmospheric pressure is stored in
millibar. That appears to be correct for the older models (Orca and iDive).
But for all the newer models (iX3M) the result is indeed a factor 10 too
large. Probably a mistake in the documentation (or a bug in the firmware).
I'll take care of fixing that.

While you are making the surface pressure change can you also add the fixed
set point data.
I am manually adding the initial fixed setpoint ppo2 to the xml file and I
also don't think that the setpoint changes get added.
You should have my ix3m-reb data from our last testing that is using fixed
setpoint and without.
