Oxygen (O2) Accumulation Bar Graph
The O2 Bar Graph (Fig. 2a) represents oxygen loading,
your relative oxygen tolerance dosage (OTU), showing the
maximum of either per dive accumulated oxygen, or 24 hour
period accumulated oxygen. As your accumulation in-
creases during the dive, segments will add to the Bar
Graph, and as loading decreases, it will begin to recede, in-
dicating that additional exposure is allowed.
NOTE: Displays associated with oxygen and
the O2 Bar Graph will only appear if FO2 has
been set at a value other than 'Air'.
Variable Ascent Rate Indicator
The Variable Ascent Rate Indicator (Fig. 2b) provides a
visual representation of ascent speed (i.e., an ascent
speedometer). Green is a 'normal' rate, yellow a 'caution'
rate, and red is 'Too Fast'. The segments of the Variable
Ascent Rate Indicator represent 2 sets of speeds which
change at a reference depth of 60 feet (18 meters). Refer
to the chart for segment values.
WARNING: At depths greater than 60 feet (18
m), ascent rates should not exceed 60 feet per
minute (18 mpm). At depths of 60 feet (18 m)
and shallower, ascent rates should not exceed
30 feet per minute (9 mpm).
