3.2 Setting the gas mixture
Before every dive, you must check if the setting of the gas mixture (portion of
oxygen) on your Aladin
®
Pro Ultra corresponds to the mixture in your tank.
Reset the mixture if necessary:
1.Switch on computer manually and check the set percentage of oxygen (O
2
%MIX).
2.Switch to O
2
%MIX input stage by bridging B and –.
3.Confirm by bridging B and E, the O
2
-value starts flashing.
4.Bridging B and + will increase the portion of oxygen (from 21% to 50%),
bridging B and – decreases the portion of oxygen.
5.Confirm with B and E. Aladin
®
Pro Ultra switches back into ready-mode.
Before every dive, make sure that the setting of
the gas mixture corresponds to the actual mixture
used. A wrong setting causes the Aladin
®
Pro Ultra
to miscalculations for this particular dive. If the
portion of oxygen is set too low this can lead to an
oxygen intoxication without warning. If the value
is set too high decompression damages due to
nitrogen saturation may occur without a respec-
tive warning from the Aladin
®
Pro Ultra.
