Sensor Warnings) when the unit can no longer
accurately measure depth.
A Depth Alarm which can be set to warn the diver
should a certain depth be exceeded is set at 130 feet
from the factory. The Depth Alarm issues an audible
alarm and the “WARNING” legend and Depth Digits
will flash on and off for five seconds. The depth alarm
is disabled if in the Decompression Mode since
flashing depth digits have another meaning in this
Mode.
The maximum depth achieved on the current dive is
shown as “MAX DEPTH”. This is updated once per
second.
“REMAIN TIME” (NDC) is the remaining time (in hours
and minutes) that the diver can stay at the current
depth without requiring decompression. A “Two
Minute Warning” will be issued when this time reaches
two minutes or less. An audible alarm will be issued
and the “WARNING” legend and “REMAIN TIME”
digits will flash. By immediately ascending to a
shallower depth, the diver may avoid a required
decompression stop.
Temperature is measured for two purposes. One is to
compensate the Depth Transducer for Temperature
variations. The other is to compensate the Nitrogen
algorithm for changes in Temperature that may affect
the body. Both of these purposes require that the
Temperature be very slow reacting, just like the Depth
Transducer and the body. This slow-reacting
Temperature is what is displayed. For Temperature
effects on the body, the amount of compensation can
be set from NORMAL to REDUCED with the Analyst
®
PC software Interface (see Analyst
®
Section), if the
diver is using a good dry-suit in cold water.
Temperature compensation starts at 75 degrees F
and gets progressively more conservative as the
temperature decreases. There is no compensation
above 75 degrees F.
Bottom Time will begin once the COMMANDER
senses that the diver has descended below five feet
(see Training Mode) and continues until the diver has
ascended above three feet. The maximum Bottom
Time displayed is 9 hours 59 minutes.
ASCENT RATE BAR GRAPH:
The Ascent Rate bar graph and alarms are active in
both the Dive Mode and Decompression Mode. The
five-segment bar graph is used to display the diver's
rate of ascent.
