Operation Manual

DataTrans Plus

PARTIAL PRESSURE OF OXYGEN

As depth increases during the dive, the partial pressure of oxygen increases.

As you approach the depth limit for the FO2 value set before that dive, the

DataTrans Plus will alert you and display the PO2 level while you reduce oxy-

gen partial pressure according to your training.

High PO2 Dive Mode

The DataTrans Plus enters the High PO2 Dive Mode when partial pressure of

oxygen becomes equal to or greater than 1.40 ATA. The audible alarm will

emit a double beep, and the PO2 value and the symbol 'PO2' will appear in the

lower portion of the display (Fig. 101). They will remain on display until par-

tial pressure of oxygen decreases below a value of 1.40 ATA.

If partial pressure of oxygen continues to increase, the value of PO2 displayed

will increase from 1.40 toward a value of 5.00 ATA in increments of '.01' ATA.

When PO2 reaches the maximum limit of 1.60 ATA, the audible alarm con-

tinuously emits one beep per second, and the large red segment of the O2 bar

graph, the PO2 value, and PO2 symbol will flash continuously as a warning

(Fig. 102) until the level of PO2 decreases below 1.60 ATA

In the event that you enter High PO2 Dive Mode, you must immediately focus

on reducing the partial pressure of oxygen by slowly ascending to a shallower
