Nitrogen Loading Bar Graph (NiBG)
The NiBG (Fig. 1a) represents tissue loading of nitrogen, showing your relative no decom-
pression or decompression status. As your depth and elapsed dive time increase, seg-
ments will add to the NiBG, and as you ascend to shallower depths, the segments will
recede, indicating that additional no decompression time is allowed for multilevel diving.
The Nitrogen Loading Bar Graph monitors 12 different nitrogen compartments simulta-
neously and displays the one that is in control of your dive. It is divided into a No Decom-
pression (normal) zone, a Caution zone (also No Decompression), and a Decompression
(danger) zone.
While you cannot provide a guarantee against the occurrence
of decompression sickness, you may choose your own personal
zone of caution based upon age, physique, excessive weight,
etc., to reduce the statistical risk.
NOTE: Displays associated with oxygen and the O2
Bar Graph will only appear if FO2 has been set at a
value other than 'Air' (e.g., a numerical value).
