Pinto BT-POM 1212 - Revision 5
Sprayer Calibration
Step 2
Determining the Actual
Speed Of Travel
Your Pinto has been factory set with a
calibration number. This should be fi ne-
tuned prior to commencement of spraying
and checked by your dealer. This is done
by traveling a known distance (usually
100 metres) and comparing the distance
measured by the Spray Controller to the
known distance. If there is a discrepancy,
the Spray Controller Manual explains how
to easily adjust the calibration number
automatically.
For the electric Spray Control, refer to
page 2.21.
For the optional MT3405 Spray Controller,
refer to page 2.23, or consult the Spray
Controller manual.
Step 3
Measure Swath Width
The spray controller requires the boom
width to be entered in 3/4/5 parts.
Measure the nozzle spacing and multiply
nozzle spacing by the number of nozzles
on each boom section to establish the
width of each boom section.
eg, 0.5m x 12 = 6m
0.5m x 12 = 6m
0.5m x 12 = 6m
Step 4
Select Nozzle Type & Size
Select Nozzle Type & Size according to:
• Chemical recommendations.
• Application rate required.
• Pressure setting.
• Swath width.
• Chosen speed of travel. (Use
actual speed of travel, refer to
step 2)
Two methods of selecting nozzle output
are:
a) Use the charts on pages 4.9 to
4.11 or the manufacturer’s nozzle
chart
b) Calculate Required Nozzle Flow
Rate.
a) Use Your Manual's Chart Or
Manufacturer’s Nozzle Chart.
Using the chart on pages 4.9 to 4.11 or
the manufacturer’s nozzle rate chart,
reference:
• Application rate (eg 50 l/ha),
• Speed of travel (eg 12km/hr), &
• Pressure setting (eg 250kPa),
fi nd the nearest nozzle to suit your
requirements.
Also check to see what speed variations
are available for applying the same rate.
See pages 4.9 to 4.11.
It is usually best to select mid range
pressure as this will allow the spray
controller to adjust pressure up or down
when speed variations occur.
Determine the actual speed of travel.
Calibration Procedure
Boom sections may vary on some booms.
NOTE
Use your own experience or a registered rate
calibration consultant to determine effective
application rates in litres per hectare.
