Tissue Loading Bar Graph - Oceanic DataTrans Plus Owner's Manual

bar graphs are located next to green, yellow, and red color coded portions of the
peripheral decal that denote normal, caution, and danger zones, respectively.
When underwater, you can quickly focus on the bar graphs to make sure that
they are in the green. You can quickly verify that you're not getting too close
to the no decompression limit or the oxygen tolerance limit, or ascending too
fast, or consuming breathing gas too fast, or running low on breathing gas.

The Tissue Loading Bar Graph
your relative no decompression or decompression status. As your depth and
elapsed dive time increase, segments will add to the graph beginning in the
lower left portion of the screen. As you ascend to shallower depths, this bar
graph will begin to recede, indicating that additional no decompression time is
allowed for multilevel diving.
The Tissue 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 green No Decompression zone (NO DECO), a yellow Caution zone (C.Z.),
and a red Decompression zone (DECO). The bar graph gives a visual represen-
tation of just how close you are to the no decompression limit with a yellow
Caution (C.Z.) Zone.
This Caution Zone portion of the bar graph (Fig. 5a) allows you to make a deci-
sion regarding safety stop duration or necessity. While you cannot provide a
