Step 4– Sensor Installation (continued)
compartment cover (Fig. 4). The sensor's LED will turn green and the
receiver will display "10.0". At this point the sensor must be installed
within 30 minutes.
5. Move the sensor to the selected site and verify signal strength as
indicted by the sensor LED color:
Green - Excellent
Yellow - Acceptable
Red (blinking) - Relocate the sensor
6. Holding the sensor parallel to the ground, push the probes and
stakes straight down through the lawn into the soil until the sensor is
pressed flat against the ground (Fig. 5).
Note: The sensor must remain in the ground for it to work. Every
12-15 minutes it will blink red indicating communication with
the receiver. There are two methods to calibrate the Soil Sensor:
Automatic or Manual. Follow the steps below:
7. At the receiver, press the Bypass button (
LED will blink and the receiver will display "CA" and an hourglass icon
(Fig. 6) until the calibration is complete. If you opted for the Manual
calibration method, this will occur when the sensor sends its next
transmission (within 12-15 minutes), at which point it will set the cur-
rent moisture level in the soil as 100% (displayed as "100"). If you opted
for the Automatic calibration method, this will occur when it completes the calibration for the
ture level in the soil as a percentage of the peak moisture level that was reached during the
calibration period.
