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
• Flowmeter
• Speed
Setting the Boom Width
The default setting is 220 inches (460 cm). 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 spray lever 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 Width position.
5. Use the Increase or Decrease calibration buttons to
change the boom width as needed.
6. Press Calibrate button until the red light turns off. You
can also exit 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 spray lever 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: If you park the sprayer on a flat, level surface and
fill the tank until the water over flows out of the top of
the tank, you will have 175 US gallons (662 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 levers and the master spray lever to
the On position. Run the booms only until the air is
purged from the line, then turn them off using the
master spray lever.
Important In order to accurately record the volume,
all three boom valves must remain on during this
procedure. Turn the booms off using only the master
spray lever. This sprayer cannot accurately calculate
tank volume when any of the boom valves are off.
5. Turn the selection dial to the Calibration Volume
position.
