Calibrating the Sonic Booms
No Parts Required
Procedure
In this procedure, you will have 20 seconds to calibrate
the sensors on the booms. The distance you set between
the sensor on each boom and the ground after the
20-second calibration period is the boom height setting
in automatic mode until the next time you calibrate the
sensor. After the 20 seconds, a self-calibrating process
occurs for up to 2 minutes, during which the controller
establishes this distance and then "learns" the flow
characteristics of the hydraulic lift cylinder valves.
Note: For uncovered booms: The default height
setting is 20 inches (51 cm) from the nozzle to the
ground. If, after setting a boom to a height different
from that of the factory default setting, you wish to
restore the calibration to the factory-default setting,
calibrate the boom with the boom in the cradle. For
covered booms: The default height setting of 20 inches
(51 cm) is for uncovered booms only. You must calibrate
the sensors on covered booms.
1. Ensure that the turf sprayer is parked and away
from any trees, buildings, vehicles, debris, and
underground utilities and plumbing.
2. Lower the booms to the horizontal position; refer to
the Operator's Manual for information on Adjusting
the Actuators to level the booms.
3. Turn off the ignition key.
4. Press the sonic boom switch on the dashboard to the
Auto position (Figure 24).

5. While pressing and holding both the Left Lower
switch and the Right Raise switch, turn the ignition
key and start the machine.
6. Release the boom switches.
Note: The green light on the sonic boom switch will
flash rapidly, indicating that the sonic boom system
is in calibration mode. You now have 20 seconds
to use the raise and lower boom switches to set the
desired distance from the booms to the ground.
After the 20 seconds, the green light will flash slowly.
7. Use the Raise and Lower switches to adjust the
height of each boom until you achieve the desired
distance from the sensor on the boom to the ground.
8. Allow the self-calibrating process to complete; wait
for the slowly flashing green light on the sonic boom
switch to stop.
Note: The self-calibrating process may take up to
2 minutes to complete. Do not interrupt the sensor
signal during the self-calibration process, such as
moving your foot under a sensor.
