Oxygen Accumulation Time Remaining (OTR)

When the ATOM is set for Nitrox operation, Oxygen Accumula-

tion (saturation or exposure) during a dive, or 24 hour period,

appears graphically as the O2 Bar Graph (Fig. 80a) when the

Alternate #2 (O2) screen is accessed. As time remaining before

reaching the Oxygen Exposure Limit decreases, segments are

added to the O2 Bar Graph.

When the amount of time remaining before reaching the Oxy-

gen Limit becomes less than the No Decompression Dive Time

Remaining, calculations for that Depth will be controlled by

Oxygen. Oxygen Time Remaining will then appear as the Dive

Time Remaining display (Fig. 81a) as signified by the symbols

O2 and TIME. As Oxygen Accumulation continues to increase,

segments will add to the O2 Bar Graph.

Air Time Remaining (ATR)

The ATOM

calculates Air Time Remaining 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

0 second period. This Rate of Consumption is then used in

conjunction with a knowledge of the Depth dependence to

predict the Air required for the diver to make a safe controlled

Ascent including any required Decompression Stops.
