GLOSSARY
The following are diving terms to become familiar with. Some apply specifically to the DataTrans Plus.
Air Dive - A dive conducted using air (approximately 21% oxygen & 79% nitrogen) as the breathing gas.
Algorithm - A step-by-step mathematical formula designed to accomplish a particular result (i.e. Dive Time
Remaining in the DataTrans Plus).
Altitude Dive - A dive made at an elevation above sea level (2,000+ ft. / 610+ m.) where a different set of no
decompression tables is used .
Breathing Gas Time Remaining - A graphic display of remaining dive time based on a calculation of cylinder
pressure, and the diver’s breathing rate and depth.
Ascent Rate - The speed that a diver ascends toward the surface.
Audible Alarm - A computer emitted tone that alerts the diver to potential danger.
Breathing Gas Consumption Indicator - A graphic display of breathing gas consumption rate.
C.Z. - Abbreviation for Caution Zone.
Caution Zone - The yellow section of the Tissue Loading Bar Graph that gives a visual warning of a diver’s
proximity to decompression.
Ceiling - See decompression ceiling.
Clean Dive - A dive preceded by 24 hours of no diving activity.
CNS - Abbreviation for the Central Nervous System of the body.
Competitive Dive - A dive conducted for profit or prize.
Compartment - A term applied to the hypothetical modeling of nitrogen absorption in the tissues (more accurate
than the term “tissue” because dive computer models have no direct relation to human tissues).
DCS - Abbreviation for decompression sickness, i.e., “the bends”.
