BAR GRAPHS

The ZEN features 3 Bar Graphs >> NiBG, O2BG, and ASC.

NiBG (Nitrogen Loading Bar Graph)

The NiBG (Fig. 22a) represents tissue loading of nitrogen, show-

ing your relative no decompression or decompression status. As

your depth and elapsed dive time increase, segments 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 simultaneously and displays the one that is in

control of your dive. It is divided into a No Decompression

(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

O2BG will only appear if FO2 has been set at a

value other than 'Air' (e.g., a numerical value).
