Surface-mode:
Activation: automatically after a dive or when changing altitude.
After a dive has been completed, Aladin
® Air Z O
2
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, depen-
ding on the gas requiring the longer time. Oxygen saturation <CNS O
2
%> is
displayed and adjusted until the value becomes 0%.
In order to save energy, Aladin
® Air Z O
2
goes into “surface-sleep”-mode after
3 minutes. The functions of surface-mode are then carried out in the back-
ground. The atmospheric pressure is measured in surface-sleep once every
minute. If the atmospheric pressure decreases, for example in case of change
of altitude, Aladin
® Air Z O
2
switches from sleep-mode or from surface-sleep
into surface-mode automatically and displays the adaptation time. The adap-
tation time is the time after which all body tissues have adapted to the ambient
pressure (= desaturation time).
Logbook-mode:
Activation: manually by contacts
Data of 19 past dives can be called up in the logbook-mode. It shows maximum
depth, dive time, preceding interval*, altitude sections, gas mixture consumpti-
on (only with pressure transmitter) and, where appropriate, alarms. A dive is
entered in the logbook if it has lasted more than 2 minutes. When the dive was
a repetitive dive then it also shows the interval which has passed since the last
dive or a preceding change of altitude. The last 37 dives and the last 175 minu-
tes of dive-profiles can be downloaded out into a MemoMouse and later from
there into a personal computer (Windows
®
).
*Preceding interval is only shown when the computer calculated that there was
a residual nitrogen uptake at the beginning of the logged dive.
