Temp (Temperature) Tab

The Temp tab screen the water temperature log. The temperature
log requires input from a temperature transducer/sensor. The most
recent temperature measured shows 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
showing 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 shown on the log. Shorter time durations shows a
greater the number of log points. Use longer time durations
to detect temperature trends, instead of immediate readings.
