Using this menu item it is possible to set the breathing gases used. The
controller allows the diver to set 5 different gases in closed circuit (CC)
mode and 5 different gases in open circuit (BO) bailout mode.
In order to set the breathing gases for the open circuit (BO) the controller
must be in BO mode, and likewise when setting the gases for the closed
circuit (CC) it must be in CC mode.
6.16.3
Define Gas
It is possible to define the percentage oxygen and helium content in each gas.
•
The ”A” in front of the gas number indicates the active gas. This cannot be deleted, i.e. setting 0% O2
and 0% helium generates an error message. However, the gas can be adjusted at any time.
•
The gases set are used for the projection of the total Time To Surface (TTS). It is therefore essential to
define only those gases that are actually available.
•
Decompression of the current active gas is correctly calculated.
•
All gases with 0% oxygen and 0% helium are automatically hidden in the ”Select Gas” menu.
•
The gases can also be adjusted underwater.
Pressing the left button ”Next Gas” results in the next gas being displayed.
The gases are numbered from 1 – 5. The sequence in which the gases are
input is irrelevant. In the ”Select Gas” menu all available gases are always
displayed in order according to their O2 content (from the highest to the
lowest). If two gases have the same O2 content then the gas with the lo-
wer helium content is brought to the front of the sequence.
By pressing the right button ”Edit” it is possible to edit the gas. First
you select wether a gas is active (= On) or not active (= Off). The active
gases are used for the projection of the total Time To Surface (TTS) and
gas switches. It is therefore essential to define only those gases that are
actually available.
After that the O2 content of the gas is set. Only one digit of the number is changed at a time. The ten’s
are always set first. Pressing the left button ”Change” results in the displayed digit being increased by 1.
After the digit has reached 9 it will revert back to 0 again. Pressing the right button (Next) once takes the
diver to the units digit.
