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 Select Units (or 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
Note:
Perform this calibration procedure each time
nozzles are changed to ensure the greatest accuracy.
The Spray Pro monitor 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.
6. Press and hold the Reset calibration button until
the display reads “0”.
7. Set the master boom switch to the On position and
run the booms until all the water is out of the tank,
then stop them using the master boom switch.
8. Compare the volume displayed on the monitor to
the volume of water you put into the tank.
• If the volumes are the same, you do not need to
calibrate the monitor any further.
• If the values are different, continue with the rest
of this procedure.
9. With the selection dial set to the Total Volume
position, press and hold the Calibrate button until
the monitor displays “CAL HOLD” and the red
light on the monitor illuminates.
The display will alternate between the total volume
reading (“HOLD” shown) and the flow calibration
value (“CAL HOLD” shown).
10. When the total volume value is displayed, use the
Increase or Decrease calibration buttons to change
it to the amount of water you put in the tank.
11. When the display begins alternating again, the
flow calibration value will have changed; write this
number down and save it. This is the calibration
value for your sprayer.
12. Press the Calibrate button until the red light turns
off. You can also exit calibration mode by driving
the sprayer.
Calibrating the Speed Sensor
The Spray Pro comes approximately calibrated for the
speed sensor. Complete the following procedure to fine
tune the speed sensor calibration:
1. Check and fill all tires; refer to Checking Tire
Pressure in the Drive System Maintenance section.
2. Fill the fresh water tank.
3. Fill the sprayer tank half-full of water.
4. Select a straight, flat track of ground that is similar
to your turf conditions.
Note:
Using a road or other paved surface could
cause an inaccurate reading when you later drive
the sprayer on turf.
5. Measure 500 feet (150 m), marking both the start
and end points.
6. Position the sprayer at the starting point.
7. Set the pump and the master boom switches to
the Off position. The monitor should display
“HOLD”.
8. Turn the selection dial to the Distance position.
9. Press and hold the Reset calibration button until
the display reads “0”.
10. Press the master boom switch to start the distance
tracking with the monitor. Drive the machine from
the start point you marked to the 500 feet (150 m)
end point.
11. Stop at the end point, set the master boom switch
to the Off position to stop the monitor.
12. Look at the distance displayed on the monitor.
• If it reads “500 feet (150 m)”, you do not need
to calibrate the monitor any further.
• If it does not read “500 feet (150 m)”, continue
with the rest of this procedure.
13. Set the parking brake.
