DIVE TIME REMAINING
One of the most important pieces of information on Aeris dive
computers is the 'Dive Time Remaining numeric display'. The dive
computer constantly monitors no decompression status and oxygen
exposure.
The Dive Time Remaining* display will indicate the time that
is more critical for you at that particular moment (i.e.; which-
ever time is the least amount available).
The specific time being
displayed is identified by the No Decompression Dive Time icon,
or the O2 Time 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 de-
compression situation. It is calculated based on the amount of ni-
trogen 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 one is closest to this maximum level is
the controlling compartment for that depth. Its resulting value will
be displayed numerically (Fig. 13a) along with the No Decompres-
sion Dive icon and graphically as the Nitrogen Bar Graph (Fig.
13b).
