Via the Analyst
®
PC Interface, the Ascent Rate Alarms
and Bar Graph can be set to the users preferences.
The first option is a VARIABLE-BY-DEPTH Ascent
Rate. When on, the Ascent Rate Alarm is determined
by depth. As the diver ascends to shallow depths, the
Maximum Ascent Rate is lowered. The Maximum
Ascent Rates and their associated depth are:
60 feet or deeper 60 feet per minute
60 to 30 feet
feet per minute equal to the depth
Less than 30 feet 30 feet per minute
If VARIABLE-BY-DEPTH is off, the Maximum Ascent
Rate Alarm and Bar Graph is specified by the user
and can be from 20 to 60 fpm, in one foot increments.
Another selection is the bar graph itself. The two
selections are either FIXED or PROPORTIONAL.
With FIXED, each of the five bars indicates an
additional 10 feet per minute of Ascent Rate
regardless of the Maximum Ascent Rate selected.
With PROPORTIONAL, each of the five bars indicate
20% (one-fifth) of the selected Maximum Ascent Rate.
For FIXED, the maximum ascent rate is 60 feet per
minute. With this setting, no bars will illuminate if a
diver is ascending at a rate less than 10 feet per
minute.
If the diver has an Ascent Rate that exceeds the
selected maximum, the entire Ascent Rate Bar Graph
will flash, and the audible alarm will sound once per
second, and the WARNING legend will illuminate.
The sensitivity or responsiveness of the Ascent Rate
may be selected via the Analyst
®
, eight different levels
of sensitivity are available.
NOTE: Customizing the Ascent Rate and Ascent
Rate Bar Graph are among many of the additional
programmable features available when using the
Analyst
®
PC Interface. Available features are
described in the section “USER CONFIGURABLE
OPTIONS”.
As shipped from the factory, the Ascent Rate is set for
VARIABLE-BY-DEPTH AND PROPORTIONAL.
