Surface-mode:
Activation: automatically after a dive or when changing altitude.
After a dive has been completed, Aladin
®
Pro Nitrox is in surface-mode. All data
belonging to the surface interval are calculated and displayed: simulation of
microbubble formation, actualization of oxygen toxicity and nitrogen saturation
of the tissues depending on the calculated skin temperature and the assumed
work load at the surface, calculation of desaturation time, and no fly interval.
Desaturation time is determined either by oxygen- or nitrogen saturation, value
becomes 0%.
In order to save energy, Aladin
®
Pro Nitrox falls into the “surface-sleep” after
3 minutes. The functions of surface-mode are then carried out in the background.
The atmospheric pressure is measured in surface-sleep once every minute. If the
atmospheric pressure decreases, for example in case of change of altitude, Ala-
din
®
Pro Nitrox switches from sleep-mode or from surface-sleep into surface-
mode automatically and displays the adaptation time. The adaptation time is the
time after which all body tissues have adapted to the ambient pressure (=
desaturation time).
