As you ascend, the TLBG segments will recede as control shifts
to slower compartments. This is a feature of the Decompression
Model that is the basis for Multilevel Diving, one of the most
important advantages that Oceanic dive computers offer.
O2 DTR (OTR)
When the OC1 is set for Nitrox operation, O2 accumulation
during a dive, or 24 hour period, is displayed as the O2BG on
an ALT screen (Fig. 72a). As time remaining before reaching
the O2 Exposure Limit decreases, segments are added to the
O2BG.
When the amount of time remaining before reaching the O2 Limit becomes less than the
NDC, calculations for that Depth will be controlled by O2 and OTR will be displayed as
DTR on the Main.
Air Time Remaining (ATR)
The OC1 calculates ATR using a patented algorithm that is based on a diver's individual
Air Consumption Rate and Current Depth.
Tank Pressure is measured once each second and an average rate of Consumption is
calculated over a 90 second period. This Rate of Consumption is then used in conjunc-
tion with a knowledge of the Depth dependence to predict the Air required for the diver
to make a safe controlled Ascent including the No Deco Deep and Safety Stops and any
required Deco Stops.
