Temp (Temperature) Tab
The Temp tab displays the water temperature log (if equipped with
a temperature transducer/sensor). The graph reads from right to left,
so the most recent temperature measured is displayed on the far right
side of the graph. The dotted lines within the graph indicate intervals
in the temperature scale and the duration of time.
Main Menu—Temp tab
The following settings are available:
•
Log and Graph Scale—sets the temperature range (in
degrees) for displaying the log. Select Auto to have the unit
determine the best range, or select a span of 2, 4, 6, 8, or 10
degrees.
•
Reset (Scale)—resets the scale range for the temperature
graph (and displays if Log and Graph Scale is set to Auto).
This is useful when the scale spans a large range due to
extreme temperature changes.
•
Log Duration—sets how fast or slow the temperature
log scrolls; the shorter the time duration, the faster the
temperature log scroll. Select a duration from 1 minute to 2.5
hours.
Alarms Tab
The Alarms tab contains settings for the unit’s alarms. (For a list of
alarms and unit messages, see page 37.) This tab is divided into two
subtabs—Sonar and System.
