GLOSSARY (continued)
DECO - Abbreviation for Decompression.
Decompression Ceiling - The shallowest depth a diver may reach upon ascent without risking decompression
sickness.
Decompression Stop - The depth(s) at which a diver must pause during ascent to allow absorbed nitrogen to
escape naturally from the tissues.
Depth Sensor - an electro-mechanical device that converts water pressure into an electrical signal, that is
converted to a visual depth display.
Diagnostic Mode - The first display seen on dive computers after initial activation during which time a self–check
for internal faults is performed.
Display - A visual readout of information.
Dive Log Mode - A computer display of previous dive information.
Dive Time Remaining - A display of the time before a diver must surface based on no-decompression status,
oxygen accumulation status, or tank pressure.
Elapsed Dive Time - The total time spent underwater during a dive between 5 feet (1.5 meters) on initial
descent to 3 feet (1 meter) on final ascent.
FO2 - The fraction (percent / 100) of oxygen (O2) in the breathing gas mixture.
Graphic Diver Interface
™
- A feature of Oceanic dive computers. Easily understandable color coded bar graphs
that indicate diver status; green = normal, yellow = caution, red = danger.
Icon - a small pictorial representation of an operational mode
Integrated Dive Computer - A dive computer that monitors and displays cylinder pressure in addition to no
decompression information.
LCD - Abbreviation for liquid crystal display, an easily viewed low voltage display usually found on dive computers
