Hiway (Highway) Tab
The Highway tab contains display settings for the Highway Page.
Refer to the “Highway Page” section on page 35.
Temp (Temperature) Tab
The Temperature tab displays the water temperature log. The
temperature log requires input from a temperature transducer/
sensor. The most recent temperature measured displays on the far
right side of the chart with the history trailing to the left. The dotted
lines within the chart indicate intervals in the temperature scale and
the duration of time.
The following settings are available:
• Temperature Scale —controls the temperature range for
displaying the log. Select Auto to have the unit automatically
determine the best range, or select a span of 2, 4, 6, 8, or 10
degrees.
•
Time Duration
—controls the number of temperature
readings displayed on the log. Shorter time durations display
a greater the number of log points. Use longer time durations
to detect temperature trends, instead of immediate readings.
