A1 USER MANUAL
7. GLOSSARY
AVG Average Depth. Calculated from the beginning of the dive or from the
time of reset.
CNS O
2
Central Nervous System Oxygen toxicity.
DESAT Desaturation Time. The time needed for the body to completely eliminate
any nitrogen taken up during diving.
Dive Time The time spent below a depth of 0.8m/3ft.
Gas Refers to the main gas that is set for the ZH-L16 ADT MB algorithm.
Local Time Current time in the local time zone.
Max Depth Maximum depth attained during the dive.
MB Microbubbles: Microbubbles are tiny bubbles that can build up in a
diver’s body during and after a dive.
MB Level One of 6 levels (L0-L5), provided by the A1’s ZH-L16 ADT algorithm.
MOD Maximum Operating Depth. This is the depth at which the partial pressure
of oxygen (ppO
2
) reaches the maximum allowed level (ppO
2
max). Diving
deeper than the MOD will expose the diver to unsafe ppO
2
levels.
Nitrox A breathing mix made of oxygen and nitrogen, with the oxygen
concentration being 22% or higher.
NO FLY Minimum amount of time a diver should wait before flying.
No-Stop Time The amount of time a diver can stay at the current depth and still make
a direct ascent to the surface without having to perform decompression
stops.
O
2
Oxygen.
O
2
% Oxygen concentration used by the A1 in all calculations.
OTU Oxygen Toxicity Unit
PDIS Profile Dependent Intermediate Stop is an additional deep stop which is
suggested by the A1 at a depth where the 5th, 6th or 7th compartment
starts off-gassing.
ppO
2
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
2
higher than 1.6bar is considered dangerous.
ppO
2
max The maximum allowed value for ppO
2
. Together with the oxygen
concentration, it defines the MOD.
Press-and-
hold The act of pressing-and-holding the button for 1 second before releasing.
SOS Mode The result of having completed a dive without respecting all mandatory
decompression obligations.
SURF INT Surface interval. The time that starts at the moment the dive is closed out.
TAT Total Ascent Time.
UTC Universal Time Coordinated. This is the primary time standard used
worldwide to regulate clocks and time. UTC correlates to your location’s
time zone through the use of offsets ranging from -12 to +14 hours.
