Calibrating the Sensor’s Height Reading (Zero Height):

•

Ensure the sprayer boom is unfolded and the sensors are located over bare soil or gravel.
Position the boom at a normal working height. Do not conduct this procedure over
standing crop or tall grass/weedy areas. It is recommended to perform this calibration in
soil mode.

•

Using a tape measure, measure the distance from the bottom of the spray nozzle to the
ground (Figure 9). Use the spray nozzle closest to the sensor. Round this measurement
to the nearest half-inch.

Figure 9: Measurement for Calibrating the Sensor Height

•

Navigate to the location measured, for example, "LOht" for the left outer sensor (Figure
8).

•

If the currently displayed height reading is not correct, adjust it using the

buttons.

The

button will increase the reading; the

button will decrease the reading.

•

To return to the Normal Operating Screen, press and hold the

button for two

seconds.

Note: To view the absolute height reading from the sensor to the ground, press and hold the

button

from the “LOht” menu. This height reading can be useful for troubleshooting purposes.
