3.2.2.3. OXYGEN DISPLAYS
If set to EAN mode the NITROX display, with all
labeled oxygen information, is shown immediately after
activation. The nitrox display shows (Fig. 3.21.):
•
oxygen percentage, labeled with O
shown in the left side of the lower display
•
set oxygen partial pressure limit, labeled
with PO
lower display
•
maximum allowed depth based on the set
oxygen percentage and partial pressure limit
•
current oxygen toxicity exposure shown
with an Oxygen Limit Fraction (OLF) bar
graph along the right side of the display.
In the Dive mode the current oxygen toxicity exposure
is always shown with an Oxygen Limit Fraction
(OLF) bar graph and the oxygen percentage labeled
with O
%. The current oxygen partial pressure labeled
2
with PO
is also shown, if selected (Fig. 3.22.). During
2
a dive, the oxygen partial pressure, labeled with PO
is always shown instead of the preselected display, if
the partial pressure is greater than 1.4 bar or the set
value (Fig. 3.23.).

Fig. 3.23. Oxygen partial
pressure and OLF displays.
There is an audible alarm and
the last segment of the bar graph
starts to blink as oxygen partial
pressure is greater than 1.4 bar
or set value, and/or the OLF has
reached 80% limit. When OLF
has reached 100%, all segments
starts to blink. If the OTU value
is higher than the CNS value, the
lowest segment blinks.
