Pro Ultra always calculates considering the gas mixture set by the
user. It is absolutely necessary to check the set mixture before each dive and
to compare it to the gas mixture actually used. Maximum deviation from the
measured mixture must not exceed 1% O
2
. A wrong gas mixture can be lethal!
5.Aladin
®
Pro Ultra disposes of a ppO
2
-warning, the default-limits of which are
set at 1.5 bar ppO
2
max. This limit can be adjusted via MemoMouse/Data Talk
in the range of 1.2 to 1.95 bar. An alternation of the ppO
2
max to higher than
1.6 bar is risky and we do not recommend it.
6.Frequently check the „oxygen-clock“ (CNS O
2
Limit), especially in the range
higher than 1.5 bar ppO
2
. Close the dive if the CNS O
2
Limit exceeds 75%.
7.Make sure you have a sufficiently long surface interval, just as when diving
with compressed air. Oxygen also needs sufficient time to leave the body. Go
on the next dive only when the CNS O
2
% has dropped below 40%.
8.Of course, Aladin
®
Pro Ultra is a personal instrument like any other diving
computer. This also applies when diving with compressed air between two
nitrox-dives. Aladin
®
Pro Ultra can be adjusted to compressed air (21% oxy-
gen) and then also includes the calculation of the CNS O
2
% in the same way
as with any other nitrox-dive.
9.Always remember: setting a wrong mixture causes either insufficient decom-
pression calculations or a too low calculation of the oxygen-toxicity!
