Calibrating the Spray Pro
Monitor
The Spray Pro monitor has a calibration mode that allows
you to change various settings to customize the display and
calibrate the monitor to your needs. You can calibrate or
change the following settings:
• Boom Width
• Units of Measure
• Speed
• Flowmeter
Setting the Boom Width
The default settings for the boom widths are 80 inches
(200 cm) for the right and left booms and 60 (150 cm) for
the center boom. This is based on 4 nozzles on the right and
left booms and 3 on the center boom all spaced 20 inches
(50.8 cm) apart. If you change the spacing of the nozzles,
you should change the boom width to reflect your changes
as follows:
1. Stop the sprayer and set the parking brake.
2. Set the master boom switch to the Off position. The
monitor displays "HOLD".
3. Press and hold the Calibrate button until the monitor
displays "CAL HOLD" and the red light on the monitor
illuminates.
4. Turn the selection dial to the Total Area position.
5. Use the Increase or Decrease calibration buttons to
select the boom for which you wish to change the
width, where 1 is the left boom, 2 is the center boom,
and 3 is the right boom.
6. Turn the selection dial to the Sub Area position.
7. Use the Increase or Decrease calibration buttons to
change the boom width as needed.
8. Repeat steps 4 through 7 for the other booms as needed.
9. Press the Calibrate button until the red light turns off.
You can also exit the calibration mode by driving the
sprayer.
Setting the Units of Measure
The default setting for the units of measure is US. You can
also change the units to SI (metric) or TURF.
1. Stop the sprayer and set the parking brake.
2. Set the master boom switch to the Off position. The
monitor displays "HOLD".
3. Press and hold the Calibrate button until the monitor
displays "CAL HOLD" and the red light on the monitor
illuminates.
4. Turn the selection dial to the Units of Measure position.
5. Use the Increase or Decrease calibration buttons to
select desired units of measure.
6. Press the Calibrate button until the red light turns off.
You can also exit calibration mode by driving the
sprayer.
Calibrating the Flowmeter
The Spray Pro comes approximately calibrated for the
flowmeter. Complete the following procedure to fine tune
the flowmeter calibration:
1. Set the parking brake.
2. Fill the sprayer tank with a known quantity of water, at
least 100 US gallons (380 L).
Note: Do not rely on the marks on the side of the tank
for measuring the water for this procedure. They are
approximate measurements, but not accurate enough for
this calibration.
3. Set the pump switch to the On position to start the
pump.
4. Set all three boom switches and the master boom switch
to the On position. Run the booms only until the air is
purged from the line, then turn them off using the
master boom switch.
5. Turn the selection dial to the Total Volume position.
