Calibration
Verify that the measured output matches the
value calculated at Step 2. For small variations
increase the spraying pressure to increase the
output or reduce the pressure to reduce output.
Spraying Output Chart
T
o use the chart draw a vertical line down from
the Travel Speed axis, at the speed you will be
using for spraying, until it intersects the diagonal
line for the Row Width of your crop. From this
point draw a horizontal line to intersect the
diagonal line for the Application Rate that you
have chosen, then draw a vertical line up to the
Total Output axis to show the total litres/min you
will need to use.
The dotted arrows on the chart show an example
using a Travel Speed of 3.5 km/hr with a Row
Width of 6m and an Application Rate of 2,000 l/ha.
The point at which the final vertical line intersects
the Total Output axis shows that the required total
output rate is 70 l/min.
