Extended notes on the setting parameters:
#1 Operational depth:
max. depth in metres at which, with the mixture used (e.g.
Nitrox 32), the set maximum oxygen partial pressure "Po2"
(usually 1.4 bar) is reached.
#2 Air pressure:
is necessary for correct calibration and calculation.
#3 Max. Partial pressure: Due to the toxicity of oxygen, it is recommended not to be
exposed to an oxygen partial pressure above 1.4 bar. This
applies under optimal conditions and health. Depending on
the condition of the day and stress (e.g. cold water), this
limit should be reduced further down (e.g. 1.2 bar)!
