4.10 Remaining Bottom Time (RBT)

22
The tank pressure is also used for the calculation of the remaining bottom time
(RBT) and the workload.
When the tank pressure reaches the set warning pressure (Dive.Log)
an audible alarm goes off and the tank symbol is shown. Default value
of warning pressure: 100 bar (1450 psi)
Do not dive any deeper. Start to ascend soon.
In case of increased workload, XP AIR displays a lung symbol and an
audible alarm goes off. (The sensitivity of workload can be changed
with Dive.Log).
In order to prevent additional saturation, reduce exertion, relax and
breathe more slowly.
If XP AIR receives no data for 30 seconds, an audible alarm goes off
and the transmitter warning appears.
If XP AIR does not receive pressure data for another 40 seconds, it
will activate another audible alarm. RBT and transmitter warning will
no longer be displayed. Instead of the tank pressure value XP AIR will
display "- - -".
Check the position of transmitter and XP AIR. Start ascending at
once.
XP AIR will switch back to its normal display as soon as new data is
received.
If the tank pressure is lower than 14bar/200psi the transmitter
switches off and XP AIR will display "---".
Do not let the tank pressure drop below 14bar / 200psi.
RBT is the time left at the current depth until the point of time when the
ascent must be started. The RBT is calculated on the basis of the current
tank pressure, breathing rate, the temperature, and the dive data so far
recorded. The RBT is based on the assumption that the tank pressure
should amount to the set pressure (default 40 bar/600 psi) at the end of
the dive. Alterations can be made with Dive.Log. A graphic representation
of RBT is on page 15.
