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 decom-
pression 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.; whichever 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 decompression situation. It is calculated
based on the amount of nitrogen absorbed by hypothetical
tissue compartments. The rates each of these compart-
ments absorb and release nitrogen is mathematically mod-
eled 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
Decompression Dive icon and graphically as the Nitrogen
Bar Graph (Fig. 13b).
