Decompression Planner
To navigate the menu follow the instructions in the picture on the left.
The RATIO iX3M integrates a complete planner for square dives for both BUL & VPM
Attention: To modify the dive parametres set the device as desired entering the
menu DIVE SET and the menu MIX
For DEPTH, TIME and
EVALUATE
make reference to “NDL Planner” (previous page)
Do you know what?:
You can keep pressed the buttons C or D to change the iX3M data more rapidly.
If the dive is outside safety parametres:
DEPTH:
It indicates the decompression stop depth (in metres if not modified)
TIME:
It indicates the decompression stop duration (in minutes)
RTIME:
It indicates the run time (time from the dive’s beginning) to the
decompression stop
MIX:
It indicates the mix used to calculate the decompression (to be set in
menu
MIX)
Press
D
to pass to the next screen to visualize CNS e OTU.
ATTENTION
: the planner uses 18 mt/min as descent speed and 9 mt/min as ascent speed for
the decompression calculations .
The iX3M will highlight in red a deco stop if the planned PpO2 is above maximum threshold.
ATTENTION
: The function Planner doesn’t carry out the profile “validation”, i.e. it doesn’t
consider a possible excess of CNS, limits on mixes’ volumetric availability, a possible isobaric
counterdiffusion due to a mix change.
To plan a technical dive properly, a suitable training is necessary.
Make reference to your instructor or to your diving certification agency you belong to in case of
doubts about planning a dive.
