BAR GRAPHS
N2/O2 (Nitrogen/Oxygen) Bar Graph
The INSIGHT features a shared Bar Graph that represents either Nitrogen loading identified by the N2
icon (Fig. 2a), or when accessed, Oxygen accumulation identified by the O2 icon (Fig. 3a). By de-
fault, the Bar Graph is referred to as the Nitrogen Bar Graph (N2BG), and represents your relative no
decompression or decompression status.
As your Depth and Dive Time increase, segments will add to the N2BG, and as you ascend to shal-
lower depths, the segments will begin to recede, indicating that additional no deco time is allowed.
The N2BG monitors 12 different nitrogen compartments simultaneously and displays the one that is in
control of your dive. It consists of 5 segments, the lower 4 represent No Decompression status and the
fifth at the top indicates a Decompression condition.
When the INSIGHT is set to operate in Nitrox mode, the Bar Graph will represent Oxygen accumula-
tion when the O2 data screen (Alternate Display) is accessed temporarily. The O2 icon (Fig. 26a) will
appear as an indication.
Regardless of which parameter the Bar Graph is representing at the time, nitrogen and oxygen calcula-
tions will continue to be performed in the background.
