P.SAFE: Level of conservativism (OC = Open Circuit Dive).
The JACK (in OC mode) uses the Bühlmann ZHL-16B
algorithm for the decompression calculation.
The conservatism of the JACK can be changed among
preset levels from 0 to 5. The levels correspond to the
following values:
Bühlmann ZHL-16 B (gradients)
GFL/GFH
0 = 93/93
1 = 90/90 standard conservatism
2 = 80/80
3 = 75/75
4 = 30/90 max linear conservatism
5 = 20/89
NOTE
Higher conservatism will ensure that the computer will perform calculations
more cautiously, decreasing the time that can pass between a given depth
without exiting the safety curve (or by extending the decompression time in
the case of dives with deco stops).
In general it is a good idea to increase the conservatism if you noticed
excessive fatigue after your most recent dive.
A hyperbaric physician can recommend how to set the conservatism,
depending on your clinical status.
