No Decompression Times are only displayed for depths where
there is at least 3 minutes of theoretical 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 PO2 of 1.60 ATA will not be displayed.
With each Depth displayed by the Dive Planner, you will see either
predicted No Decompression Limits (NDLs) based upon your pre-
vious dive profiles (if calculated to be nitrogen controlled), or pre-
dicted Oxygen Tolerance Limits (OTLs) based upon either a single
dive exposure or your 24 hour accumulation of oxygen (if calcu-
lated to be oxygen controlled).
If the Nitrogen Bar Graph is displayed (Fig. 41), that next dive is
calculated to be controlled by Nitrogen loading. If the O2 Bar
Graph and O2 symbol are displayed (Fig. 42), it is calculated to be
controlled by Oxygen loading.
NOTE: The ATMOS 2 will store oxygen accumulation cal-
culations for up to 10 dives conducted during a 24 hour
period. If the maximum limit for oxygen loading has been
exceeded for that day (24 hour period), all of the seg-
ments of the O2 bar graph will be displayed flashing .
Depth/Time values will not appear until the O2 bar graph
recedes into the green (normal) zone (i.e., your daily oxy-
gen dosage decreases an amount equivalent to the
amount accumulated during the latest dive completed).
