Air Z also measures the atmospheric pressure in sleep-mode. If the
computer detects a higher altitude section, it switches into surface-mode auto-
matically. Desaturation time indicated at this moment refers to adaptation time
at this altitude. If diving starts within this adaptation time, Aladin
®
Air Z treats
it as a repetitive dive, since the body still has a higher saturation.
The entire altitude range is divided into four sections which are influenced by meteorological circum-
stances. That is why the following altitude sections overlap on their fringes. The altitude section is indi-
cated at the surface, in the logbook and in the dive planner by stylized mountains, if a mountain lake
altitude is reached. Section 0 is not indicated. In the following, you can see the approximate altitude ranges
of the four sections:
