DataTrans Plus
If FO2 was set for a numerical value, FO2 and the value set will appear as the
first screen (Fig. 59), followed by a screen showing the maximum depth that
can be achieved for an oxygen partial pressure of 1.60 ATA for that FO2 (Fig.
60).
The DataTrans Plus then scrolls through the Pre Dive Planning Sequence
(PDPS), displaying a sequence of depths from 30 to 160 feet (9 to 48 meters) in
10 foot (3 meter) increments. With each depth display, you will see either 'pre-
dicted' no decompression limits based upon your previous dive profiles (if cal-
culated to be nitrogen controlled), or 'predicted' oxygen tolerance limits based
upon either a single dive oxygen dose or your 24 hour accumulation of oxygen
(if calculated to be oxygen controlled).
Information displayed includes Previous Dive #, Depth, Dive Time available at
that depth (which includes descent time at a rate of 120 ft/min), Plan Mode
icon, and the message MODE:PLAN.
No decompression times are only displayed for depths where there is at least 3
minutes of dive time available at the depth, taking into account a descent rate
of 120 feet (36 meters) per minute. Depths greater than the maximum depth
that can be achieved with a partial pressure of oxygen (PO2) of 1.60 ATA will
not be displayed.
