CHROMIS USER MANUAL
Average depth, calculated from the beginning of the dive or from the
time of reset.
Central Nervous System oxygen toxicity.
Desaturation time. The time needed for the body to completely eliminate
any nitrogen taken up during diving.
The time spent below a depth of 0.8m/3ft.
Refers to the main gas that is set for the ZH-L8 ADT MB algorithm.
the time in the local time zone.
Maximum depth reached during the dive.
Microbubble. Microbubbles are tiny bubbles that can build up in a
diver's body during and after a dive.
One of the six steps, or levels, in SCUBAPRO's customizable algorithm.
Maximum Operating Depth. This is the depth at which the partial
pressure of oxygen (ppO
(ppO max). Diving deeper than the MOD will expose the diver to unsafe
2
ppO levels.
2
Refers to a dive in which more than one breathing gas is used (air and/
or Nitrox).
A breathing mix made of oxygen and nitrogen, with the oxygen
concentration being 22% or higher. In this manual, air is considered as
a particular type of Nitrox.
Minimum amount of time the diver should wait before taking a plane.
This is the time that a diver can stay at the current depth and still
make a direct ascent to the surface without having to perform
decompression stops.
Oxygen.
Oxygen concentration used by the dive computer in all calculations.
Profi le Dependent Intermediate Stop is an additional deep stop which
is suggested by Chromis at depth where 3rd, 4th or 5th compartment
starts off gassing.
Partial pressure of oxygen. This is the pressure of the oxygen in the
breathing mix. It is a function of depth and oxygen concentration. A
ppO higher than 1.6bar is considered dangerous.

The maximum allowed value for ppO

The act of pressing and releasing one of the buttons.
The act of pressing and holding one of the buttons for 1 second before
releasing it.
Surface interval. Elapsed time since your last dive has ended.
