GRAPHIC DIVER INTERFACE

™

NOTE: Displays associated with oxygen and the O2 bar graph

will only appear if FO2 has been set at a value other than 'Air'.

Three bar graphs referred to as the Graphic Diver Interface™ are located around

the perimeter of the DataPlus' LCD (Fig. 25). They are color coded green,

yellow, and red to denote normal, caution and danger zones, respectively. The

Graphic Diver Interface allows you to make quick status checks underwater of

your no decompression status, oxygen loading status, and ascent rate. Keeping

these bar graphs in the green at all times will reduce your exposure to decom-

pression sickness, oxygen toxicity, and the effects of an excessive ascent rate.

TISSUE LOADING BAR GRAPH

(TLBG)

The Tissue Loading Bar Graph

(TLBG) represents nitrogen loading, showing

your relative no decompression or decompression status. As your depth and

bottom time increase, segments will add to the graph in an arc beginning from

the lower left. As you ascend to shallower depths, the TLBG will begin to recede,

indicating that additional no decompression time is allowed for multilevel diving.

The TLBG also assists you with managing decompression by filling a large red

'ceiling stop required' segment, which is explained in more detail in the Handling

the Extremes section.
