Calibrating The Spray Pro Monitor - Toro multi-pro 1200 Operator's Manual

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 [CAL] 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 [+] or [–] buttons to change the boom width as
needed.
6. Press [CAL] 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 [CAL] 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 [+] or [–] buttons to select desired units of
measure.
6. Press [CAL] 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 164 US gallons (621 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.
5. Turn the selection dial to the Calibration Volume
position.
6. Press and hold [RESET] until the display reads "0."
7. Set the master spray lever to the On position and run the
booms until all the water is out of the tank, then stop
them using the master spray lever.
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. Turn the selection dial to the Flowmeter Calibration
position.
10. Press and hold [CAL] until the red light on the monitor
illuminates.
The display will alternate between the flowmeter
calibration value (indicated by the word"CAL" on the
monitor) and the calibration volume.
11. When the calibration volume is displayed, use the [+] or
[–] buttons to change it to the amount of water you put
in the tank.
12. When the display begins alternating again, the
flowmeter calibration value will have changed; write
this number down and save it. This is the calibration
value for your sprayer.
