Ascent Rate Bar Graph:
The Ascent Rate Bar Graph is comprised of a vertical five-segment bar. With the
optional Analyst Personal Computer Interface, you can select this bar graph to either
represent the speed of your ascent or a percentage of the selected maximum ascent
rate.
SPEED: With this option, each bar of the graph represents an additional 10
feet per minute of speed. For example, if you were ascending between 11 and
20 feet per minute, one bar segment would illuminate. If you were ascending
between 21 and 30 feet per minute, two bar segments would illuminate, and so
on with all five bar segments appearing when ascending between 51 and 60
feet per minute. The performance of this option remains the same regardless
of the type or the maximum ascent rate selected.
PERCENTAGE: With this option, each bar of the graph represents an addi-
tional 20% of the maximum ascent rate selected. For example, if you had
selected a fixed ascent rate limit of 30 feet per minute, each bar segment
would represent an additional ascent rate of 6 feet per minute. (6 is 20% of 30)
This option is especially useful if a variable ascent rate is selected. Regard-
less of the depth and associated maximum ascent rate, you will quickly be
able to identify if you are approaching 100% maximum limit.
The Ascent Rate Bar Graph is set at the factory to display SPEED.
Batt:
This legend is illuminated when either the battery in the TU or WU is low. If this legend
is flashing, then the battery in the TU is low. If the legend is on steady, then the battery
in the WU is low.
NOTE: If both batteries are low, then the BATT legend will flash. Upon replace-
ment of the TU’s batteries, the BATT legend will then be on steady indicating that
the WU’s batteries do need to be replaced.
Bottom:
This is the total bottom time ( displayed in hours and minutes ) calculated for a
particular dive. Should a diver ascend to the surface, remain on the surface for less
than 10 minutes and then commence another dive, the bottom time will continue to
increment as though there was no time spent on the surface.
Surface Mode: The bottom time of your last dive is provided to you on the Alternate
Display in hours and minutes. At the start of a new dive day, the bottom time
will be 0:00.
Logbook Mode: The bottom time for the profile viewed is displayed on the Main display..
Gauge Mode or Emergency Decompression Mode or Subsurface Mode: Your dive
computer begins to count your bottom time when you have descended below
five feet. Bottom time continues to be counted until you have ascended above
three feet. This time is expressed in hours and minutes.
