NiTek Plus Dive Computer User Manual 3
Features and functions
The NiTek Plus incorporates a number of important modes and
features:
• The NiTek Plus turns on automatically upon descent
• On the surface, the NiTek Plus constantly displays a
minimum of date and time
• The NiTek Plus is capable of displaying two different times
through an alternate time display mode
• The NiTek Plus uses easily accessible and highly reliable
push buttons instead of exposed electrical contacts
• The NiTek Plus can be programmed to monitor exposure to
two different gas mixtures during a dive. Mix1 is
programmable for mixtures ranging from air (EAN21) to
EAN50. Mix2 is programmable for mixtures ranging from
air (EAN21) to EAN99. Underwater, NiTek Plus users can
switch between mixes at the push of a button.
• The NiTek Plus is capable of functioning up to a depth of
328 feet (100 meters) when in dive computer mode and 656
feet (200 meters) when in gauge mode
• The NiTek Plus automatically adjusts for altitudes up to
19,680 feet (6,000 meters)
• The NiTek Plus displays a variety of data underwater
including: date, time of day, current and maximum depths,
no-decompression dive time elapsed and remaining, and
water temperature
• The NiTek Plus 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 Plus helps to alert the diver to a number of possibly
hazardous situations including: violation of ascent rate, no-
decompression state, and whether mandatory decompression
