6. Run the tractor at the RPM selected in
Section 4.9.1. Operate the chemical circuit
pump at the desired pressure and meas-
ure the time that it takes to spray a quart or
liter through each nozzle.
Use Table 2 to determine flow rate for the
nozzle.
NOTE
Calibration cups are available
from most agricultural offices or
weed supervisors.
IMPORTANT
If the Controller cannot produce
the required pressure in the
chemical circuit, decrease the
agitation flow to reset the system
and try again.

4.9.2
CONTROLLER CALIBRATION
The controller must be set and calibrated for your
specific machine. Refer to the Controller manual
and follow its Calibration procedure. Use the
same controller settings during sprayer compo-
nent calibrations as used in the field.
The automatic controller will adjust the chemical
circuit to provide for a uniform application rate
when ground speed changes up to + 20%. How-
ever the system must be calibrated to determine
the application rate at the nominal starting point.
4.9.3 NOZZLE CALIBRATION
Consult your dealer or the factory to determine the
type of nozzles on your machine and their specific
nominal flow rate. To determine or set the appli-
cation rate, the flow rate of solution through the
nozzles must be known. Operate the tractor at
the same RPM and hydraulic setting as if running
in the field. Start with the chemical circuit pres-
sure at 20 psi. Increase or decrease pressure as
required to obtain desired flow rate.
1. Remove all the nozzles from the sprayer.
2. Use clean water to wash each nozzle and
clean the check valve.
3. Reinstall the nozzles in the booms.
IMPORTANT
Never calibrate nozzles with
active chemical in the tank. The
solution can contaminate workers,
the workplace and the environ-
ment.
4. Add clean water until the tank is 1/2 full.
5. Place a calibration cup under all the nozzles
on each boom.
