Regardless of which parameter the Bar Graph is representing at the time, nitrogen calcula-
tions (if in NOR Nitrox or FRE Mode) and oxygen calculations (if in NOR Nitrox Mode)
will continue to be performed in the background.
While in NOR Mode, displays associated with oxygen and the O2 Bar Graph will be
displayed if FO2 has been set at a value other than AIR (e.g., a numerical value) and the
ALT 2 screen that displays oxygen related data is accessed.
When the oxygen data ALT screen is accessed during a NOR Nitrox dive, the Bar Graph
will show the maximum of either per dive or 24 hour period accumulated oxygen.
As oxygen accumulation (or saturation) increases during a NOR Nitrox dive, segments will
add to the O2 Bar Graph, and as saturation decreases, it will begin to recede, indicating
that additional exposure is allowed for that dive and 24 hour period.
The DataMask will store calculated oxygen accumulation for up to 10 dives conducted
during a 24 hour period. If the maximum limit for NOR Nitrox dive oxygen accumulation
has been exceeded for that day (24 hour period), all of the segments of the O2 Bar Graph
will be displayed flashing (Fig. 7).
Depth/Time values will not appear in Plan Mode until the O2
Bar Graph recedes into the normal zone (lower 4 segments)
indicating that your daily oxygen saturation has decreased an
amount equivalent to the amount accumulated during the latest
dive completed.
