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.
