Using the NiTek X
NiTek X Dive Computer User Manual v1.1 44
Altitude Operation
The NiTek X adjusts automatically for diving at altitudes of up
to 19,685 feet (6,000 meters).
The NiTek X monitors altitude information in all modes, except
PC transfer mode. Upon arriving at altitude, the NiTek X’s PGT
bar graph may show that there is excess nitrogen present, even
though you may not have made any dives in the preceding 24
hours.
If you have obtained the altitude specialty diver training (which
everyone should do before diving at altitudes substantially above
sea level), you already understand that this should be expected.
By ascending to a higher altitude from a lower one, your body
has more nitrogen saturated in body tissues than would be
present had you spent the preceding 24 hours at the higher
altitude. By displaying residual nitrogen and a surface interval,
your NiTek X is merely reflecting this fact.
Prior to using the NiTek X at altitudes substantially above sea
level, you should find out what the actual altitude of your dive
site is.
If the level of residual nitrogen calculated by the NiTek X is
unusually high (seven or eight bars) when going to altitude, the
computer will be unable to enter dive mode. Avoid taking the
computer to altitude when residual nitrogen levels are this high,
and do not enter the water until nitrogen levels have dropped
substantially.
Note Do not place the NiTek X in dive mode when
making sudden, substantial changes in altitude, such as
when flying in an airplane. This can be caused by storing
the NiTek X with wet dive gear, which may cause it to
turn on and enter dive mode. This can interfere with the
computer’s ability to function accurately.
