remaining if you are in a decompression or violation mode.

The DataTrans Plus calculates Breathing Gas Time Remaining using a pat-

ented algorithm that is based on a diver's individual breathing gas consump-

tion rate and depth. Tank pressure is measured once each second, and an av-

erage rate of consumption is calculated over a 90 second period. This rate of

consumption is then used in conjunction with a knowledge of the depth depen-

dence to predict the breathing gas required for a safe ascent including any re-

quired decompression stops.

Breathing gas consumption and depth are continuously monitored, and

Breathing Gas Time Remaining reflects any change in your circumstances.

For example, when a buddy starts breathing from your octopus or you sud-

denly find yourself swimming against a strong current and begin breathing

more rapidly, the DataTrans Plus will recognize this change and adjust your

Breathing Gas Time Remaining accordingly.

Remember, the Breathing Gas Time Remaining is the time you can remain at

the present depth and still surface with the tank pressure reserve (Gas Alarm

Set Point) that you set during setup. When Gas Time Remaining indicates

zero, you should immediately initiate a controlled ascent. However, there is no

reason to panic, the DataTrans Plus has allowed for the breathing gas neces-

sary for a safe ascent including any emergency decompression stops.
