DTR (DIVE TIME REMAINING)
The ProPlus X constantly monitors No Decompression status and O2 Accumulation, and will display whichever time is the least amount available as
DTR on the No Decompression Dive Main screen. The time being displayed will be identified by the NDC (no decompression) or OTR (Oxygen Time
Remaining) icons.
NO DECOMPRESSION
No Decompression is the maximum amount of time that you can stay at your present depth before entering decompression. It is calculated based on
the amount of nitrogen absorbed by hypothetical tissue compartments. The rates each of these compartments absorb and release nitrogen is math-
ematically modeled and compared against a maximum allowable nitrogen level.
Whichever compartment is closest to this maximum level is the controlling compartment for that depth. Its resulting value NDC (no decompression)
will be displayed. It will also be displayed graphically as the Tissue Loading Bar Graph, see Bar Graphs later in this section.
As you ascend, the Tissue Loading Bar Graph will recede as control shifts to slower compartments. This is a feature of the decompression model that
is the basis for multilevel diving, one of the most important advantages that Aqua Lung dive computers offer.

OTR (OXYGEN TIME REMAINING)
When set for nitrox operation, O2 SAT (Oxygen Saturation) during a dive is displayed on the More Dive Data screen as a percentage of allowed
saturation identified by O2 SAT. The limit for O2 SAT (100%) is set at 300 OTU (Oxygen Tolerance Units) per dive or 24 hour period. See the chart
at the back of this manual for specific times and allowances. O2 SAT and OTR (Oxygen Time Remaining) values are inversely related; as the O2
SAT value increases the OTR (Oxygen Time Remaining) value decreases.
When the OTR (Oxygen Time Remaining) value becomes less than the No Decompression calculations for the dive, DTR (Dive Time Remaining) will
be controlled by O2 SAT and the OTR (Oxygen time Remaining) value will be displayed as the DTR on the Dive Main screen, identified by the OTR
icon.

BAR GRAPHS
The ProPlus X features two specific bar graphs.
1. The one on the left represents nitrogen loading. It is referred to as TL (Tissue Loading) Bar Graph.
2. The one on the right represents ascent rate. It is referred to as the AR (Ascent Rate) Bar Graph.
