DataTrans Plus
GAS TIME REMAINING DURING DECOMPRESSION
Breathing Gas Time Remaining will fluctuate throughout your dive, decreas-
ing as you dive deeper or breath heavier, and increasing as you ascend to shal-
lower depths or relax your breathing efforts. If you inadvertently exceed no
decompression limits, the DataTrans Plus will provide critical information re-
garding your remaining breathing gas supply.
Once you enter Decompression Mode, you will need to refer to the Gas Time
Remaining bar graph for Breathing Gas Dive Time Remaining information.
When Breathing Gas Time Remaining decreases to 5 minutes, the tank pres-
sure numerals will flash and a Double Beep will sound (Fig. 87). This means
that only 5 minutes remain before your breathing gas supply will be reduced to
the minimum level necessary to perform the required decompression stops and
still provide a tank pressure reserve upon surfacing.
When the Breathing Gas Time Remaining decreases to zero minutes, the Au-
dible Alarm will continuously beep once per second (Fig. 88), signaling the
need for an immediate safe ascent to your first decompression stop. However,
there is no need to panic. The DataTrans Plus has allowed for the breathing
gas you will consume during a safe ascent including the required decompres-
sion stops and still provide the surfacing tank pressure reserve you chose (en-
tered) during setup, e.g. 500 psi.
