7. Start the tractor.
8. Set the PTO speed according to the values in the fertiliser chart.
9. Open the left metering slide for the calibration test time stipulated before from
the tractor seat.
10. Close the metering slide when this time has elapsed.
11. Switch off the PTO shaft and tractor engine and lock them to prevent unau-
thorised starting.
12. Determine the fertiliser weight (taking into consideration the empty weight of
the collection vessel).
13. Compare the actual quantity with the target quantity.
 Actual output volume = target outlet volume: application rate stop/stopper
is set correctly. End calibration test.
 Actual outlet volume < target outlet volume: Set the application rate
stop/stopper to a higher position and repeat the calibration test.
 Actual outlet volume > target outlet volume: Set the application rate
stop/stopper to a lower position and repeat the calibration test.
Calculation with formula
The position of the application rate stop/stopper can also be calculated using the
following formula:
6. Position a collection vessel
under the left outlet.

NOTICE
You can use the percentage scale to reset the position of the application rate
stop/stopper. For example, if the calibration test weight is down by 10%, the ap-
plication rate stop/stopper is set to a 10% higher position (e.g. from 150 to 165).
