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
(2.03 m) for the right and left booms and 60 (1.524 m)
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".
