3.3.2. Oxygen Displays
If set to NITROX Mode the NITROX display, with all
labeled oxygen information and the label NITROX, is
shown after activation and before the Dive Planning
mode. The NITROX display shows (Fig. 3.20):
• the oxygen percentage labeled with O
2
% is
shown in the left side of the center window
• the set oxygen partial pressure limit labeled
with PO
2
is shown in the upper right display
• the maximum allowed depth based on the
set oxygen percentage and partial pressure
limit
• the current oxygen toxicity exposure shown
with an Oxygen Limit Fraction (OLF) bar
graph along the left side of the display
(instead of the CBT).
In the DIVE Modes, the oxygen percentage labeled
with O
2
% and the current oxygen toxicity exposure
shown with an Oxygen Limit Fraction (OLF) bar
graph are shown (Fig. 3.21 and 3.22). During a dive,
the oxygen partial pressure labeled with PO
2
is also
shown instead of the maximum depth in the upper
right display, if the partial pressure is greater than
1.4 bar or the set value (Fig. 3.23).
Fig. 3.22 Diving in the NI-
TROX Mode. The O
2
% is set
to 32%.
Fig. 3.23 Oxygen partial pres-
sure and OLF displays. There is
an audible alarm as the oxygen
partial pressure is greater than
1.4 bar or the set value and the
OLF has reached the 80% limit.
