Rbt When Diving With More Than One Gas Mixture - Uwatec Galileo sol User Manual

NOTE:
If after Galileo has changed the
decompression schedule to refl ect the
missed gas switch, you descend again
below the MOD for the gas mixture you
did not switch to, Galileo reintroduces
that gas into its calculations and the
decompression schedule
accordingly. This is accompanied by
the display message INCLUDING T2
(or TD) AGAIN for 4 seconds.
3.7.5.3 Belated gas switch
You can catch up on a planned gas mixture
switch at any time by selecting the gas
manually. Press and hold the left button to
start the gas switch procedure. Galileo will
show the message SWITCH TO GAS T2
(or TD), and its MOD. This helps you verify
that you are performing a switch to a safe
gas. The button labels change to SAVE (left)
and >> (middle). Use >> to choose the next
tank you want to use, then press or press
and hold SAVE to confi rm the switch.
Galileo will display the message SWITCH
TO GAS T2 (or TD) SUCCESSFUL
and adapt the decompression schedule
accordingly. If you want to interrupt the
gas switch procedure, press and hold the
right button.
3.7.5.4 Manual gas switch at a depth
deeper than its MOD
There may be situations in which you have
no other choice but to switch to a different
gas mixture although you are below the
MOD for that mixture. Galileo does not
prevent you from doing this, but the MOD
alarm will immediately go off.
NOTE:
It is not dangerous to switch the
computer to a gas mixture below its
MOD, but rather it is dangerous to
breathe a gas mixture below its MOD.
Galileo alerts you of the imminent
danger when you do so.
3.7.5.5 Submerging below the MOD
changes 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.
3.7.6 RBT when diving with more
than one gas mixture
Galileo determines the RBT based on
your breathing pattern. The tanks with
the various gas mixtures you have with
you may be of different sizes, therefore
the RBT calculation cannot be extended
to all tanks at once since your breathing
pattern will be different for each tank. Since
Galileo performs several decompression
calculations simultaneously for all possible
combinations of gas mixtures, the RBT
calculation references the decompression
calculation that considers only the gas you
are currently breathing from.
- If you have programmed 2 or 3 gases
and are currently breathing from T1,
the RBT will be for the decompression
schedule that considers T1 only.
- If you have programmed 3 gases and
are currently breathing from T2, the RBT
will be for the decompression schedule
that consider T2 only.
