DIVE TIME REMAINING
One of the most important pieces of information on Aeris dive computers is the 'Dive Time Re-
maining numeric display'. The
ATMOS ai
constantly monitors no decompression status, oxygen
accumulation, and breathing gas consumption rate.
The Dive Time Remaining* display will indicate the time that is more critical for you at that
particular moment (i.e.; whichever time is the least amount available).
The specific time be-
ing displayed is identified by the No Decompression Dive Time icon, the O2 Time icon, or Tank
icon.
(* This unique feature has been granted U.S. Patent No. 4,586,136.)
No Decompression Dive Time Remaining
No Decompression Dive Time Remaining is the maximum amount of time that you can stay at
your present depth before entering a decompression situation. 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 mathematically modeled and compared against a maximum allow-
able nitrogen level. Whichever one is closest to this maximum
level is the controlling compartment for that depth. Its resulting
value will be displayed numerically (Fig. 10a) along with the No
Decompression Dive icon and graphically as the Nitrogen Bar
Graph (Fig. 10b).
As you ascend from depth following a dive that has approached
the no decompression limit, the Nitrogen Bar Graph will recede as
control shifts to slower compartments. This is a feature of the de-
compression model that is the basis for multilevel diving, one of
the most important advantages that Aeris dive computers offer.
