8 Calibration
For precise control of the discharge amount, we recommend running a new calibration test every time
the spreading material type is changed.
Execute the calibration:
• Before spreading for the first time
• If the spreading material quality has changed significantly (moisture, high dust content, granulate
damage)
• If a new spreading material is used
The calibration must be conducted while the PTO shaft is running at a standstill or during travel over a
test track.
8.1 Determining the output volume
• Calculate the nominal output volume before starting the calibration test.
The exact forward speed must be known to calculate the nominal output volume.
To calculate the nominal output volume per minute, you will require the following:
• Forward speed,
• Working width,
• Desired application rate
Example: You wish to calculate the nominal output rate.
• Your forward speed is 3 km/h ,
• The working width is specified to be 4 m ,
• The application rate should be 50 g/m².
If you cannot find your values in the spreading material chart, the nominal output rate is to be
determined by means of a formula.
Nominal output
rate (kg/min)
=
Forward speed (km/h) x working width (m) x application rate
(g/m2)

Example
3 km/h x 4 m x 50 g/m2
= 10 kg/min
