MATRIX Dive Computer
16
NOTE
- If you dive using just one gas, select G1
and deselect the other two.
- For dives with two gases, select G1 and
G2 and deselect the third.
- When enabling G2 and G3, you must first
define G2 and then G3.
- You cannot activate G3 without first
having activated G2.
- G2 cannot have an oxygen percentage
higher than G3.
- If you set G2 to OFF, G3 will
automatically be set to OFF also.
- The MOD for G2 and G3 is the switch
depth for the corresponding gas. This
is what Matrix uses for its calculation,
alarms and suggested switch points.
3.5.1 SETTING MORE THAN ONE GAS
The characteristics of the gases must be
entered in the computer before the dive. It will
then be your responsibility to tell Matrix which
gas is currently being used during the various
phases of the dive.
To use multiple gases, you will need to enable
the gases and set the oxygen percentage and
the ppO
2
max for each one. This is done in the
same way as for G1, with the difference that
for G2 and G3 you can turn a gas ON or OFF.
Keep in mind that the MOD for G2 and G3 is
the depth at which Matrix will prompt you
to perform the gas switch (see section 3.5.2
below).
You can verify all set gases from the pre-dive
screen by pressing and holding the top right
button.
3.5.2 SWITCHING GAS
During Nitrox dives with the gas switching
function enabled, press and hold the top right
button to call up the gas switch screen. This
screen lists all set gases, their O
2
% and MOD.
Matrix always begins the dive with G1,
which has the lowest percentage of oxygen.
When during the ascent you reach the depth
corresponding to the MOD of G2, Matrix
sounds an audible signal and displays the
message GAS 1 -> GAS 2 at the bottom of the
screen.
NOTE
- Matrix will allow the change only if
the depth is shallower than the MOD
corresponding to the set ppO
2
max.
- Matrix will not allow the gas switch if you
are deeper.
- The message at the bottom of the screen
remains only for 20 seconds. You can
however call up the gas switch screen at
any time, and switch to another gas as
long as your depth allows the gas to be
activated.
- The same process is repeated when
you approach the MOD for G3 with the
message GAS 2 -> GAS 3.
- If you have set G1, G2 and G3 and have
not switched from G1 to G2, once you
reach the MOD for G3 the display will
prompt the message GAS 1 -> GAS 3
NOTE
You can reach the gas switch screen at any
time during the dive, for instance to check
the planned switch point of G2 and G3.
Once inside this display, use the buttons on the
right side to move up or down between gases,
then press and hold the top right button to
activate the gas. This brings you back to the
default computer display. The decompression
calculation will reflect the switch in breathing
gas. In addition, the display will now show the
oxygen concentration of the new gas.
NOTE
- You can exit this mode without changing
the gas by pressing the top left button.
- If there is only one gas set, the computer
will not enter this display.
3.5.3 SPECIAL SITUATIONS
3.5.3.1 SWITCHING BACK TO A GAS MIXTURE
WITH LOWER OXYGEN CONCENTRATION
There may be situations in which you have
to switch back to a gas with lower oxygen
concentration than what you are currently
breathing. This can happen for instance if you
want to descend deeper than the MOD for the
current gas, or if for instance you have run out
of gas in G3 during the decompression. To do
so, simply press the top left button to call up
the gas switch screen. Use the right buttons to
choose another gas, then press and hold the
top right button to activate it.
3.5.3.2 SUBMERGING BELOW THE MOD
AFTER A GAS SWITCH
If after having switched to a gas mixture with a
higher oxygen concentration you inadvertently
drop again below the MOD for that mixture,
the MOD alarm will immediately go off. Either
switch back to a gas mixture suited for that
depth, or ascend above the MOD for the gas
mixture you are breathing from.
3.6 BOTTOM TIMER MODE
When Matrix is set to bottom timer mode, it
will only monitor depth, time and temperature,
and will not carry out any decompression
calculation. Maximum displayed dive time
in gauge mode is 999 minutes. You can only
switch to bottom timer mode if the computer is
completely desaturated. All audible and visual
alarms, other than the low battery alarm, are
turned off.
WARNING
Dives in bottom timer mode are performed
at your own risk. After a dive in bottom
timer mode you must wait at least 24
hours before diving using a decompression
computer.
