Temp (Temperature) Tab
Displays the water temperature log (if equipped with a temperature transducer/sensor). The graph reads
from right to left, so that 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.
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. Useful when the scale spans a
large range due to extreme temperature changes. Only shows if Log and Graph Scale is set to ‘Auto’.
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.
