Implementing the calibration test
WARNING!
Risk of injury due to chemicals
Escaping fertilizer may lead to injury to eyes and nasal mucous membranes.
u
Wear safety goggles during calibration.
u
Before running the calibration test, ensure that all people leave the hazard zone of the
machine.
Requirements
•
The metering slide is closed.
•
PTO and tractor engine are switched off and locked to prevent unauthorized starting.
•
An adequately sized hopper is ready for collecting the discharged spreading material.
The hopper’s empty weight is known.
•
Using the spreading material chart, the pre-set values for the metering slide stop are determined
and known.
•
There is sufficient spreading material in the hopper.
Select the calibration time to obtain the maximum possible spreading material discharge quantity.
The higher the quantity, the higher the precision of the measurement (e.g., Nominal output rate:
10 kg/min, calibration test time: 3 min, used spreading material quantity: 30 kg).
