BAR GRAPH
The ATOM features one shared Bar Graph that represents either
nitrogen loading, or when accessed, oxygen accumulation. By
default the Bar Graph (Fig. 25a), referred to as the Tissue
Loading Bar Graph (TLBG), represents your relative no decom-
pression or decompression status.
As your Depth and Elapsed Dive Time increase, segments will
add to the TLBG, and as you ascend to shallower depths, the
segments of the TLBG will begin to recede, indicating that
additional no decompression time is allowed.
The Tissue Loading Bar Graph 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 ATOM is set to operate in NORM Nitrox mode, the
Bar Graph will represent oxygen accumulation when the oxygen
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 (if NORM or FREE) and oxygen (if NORM)
calculations will continue to be performed in the background.
