Introduction
NiTek Dive Computer User Manual 3
Features and functions
The NiTek incorporates a number of important modes and
features:
• The NiTek turns on automatically upon descent
• On the surface, the NiTek constantly displays a minimum of
date and time
• The NiTek uses easily accessible and highly reliable push
buttons instead of exposed electrical contacts
• The NiTek can be programmed to monitor exposure to either
air or a Nitrox mixture from EAN22 to EAN50 during a dive
• The NiTek is capable of functioning up to a depth of 328
feet (100 meters)
• The NiTek automatically adjusts for altitudes up to 19,685
feet (6,000 meters)
• The NiTek displays a variety of data underwater including:
time of day, current and maximum depths, no-
decompression dive time elapsed and remaining, and water
temperature
• The NiTek displays data specifically related to the use of
Enriched Air Nitrox (EANx) including: fraction of oxygen
(FO2) setting, partial pressure of oxygen (PO2), and an
oxygen limit index (OLI) representing the cumulative effect
of a diver’s exposure to elevated PO2s (the theoretical “CNS
clock”) as a bar graph
• Through a combination of audible and visible alarms, the
NiTek alerts the diver to a number of possibly hazardous
situations including: violation of ascent rate, no-
decompression state, and whether mandatory decompression
stops are necessary or if the diver has ascended above a
mandatory stop ceiling. Nitrox specific warnings occur when
the diver approaches or exceeds a limiting PO2 of 1.6
atmospheres, and when cumulative exposure to elevated
PO2s exceeds recommended limits.
• The NiTek can be programmed to display data in Imperial or
metric units
