Carrying out calibration test
Generally speaking you ought to carry out the calibration test on
farmyard.
With the optional ED II follow the procedure as described in the ED II
user manual. Below follows the procedure for spreaders of manual
and hydraulic operation.
Work carefully to arrive at an optimal result!
Switch the tractor off, remove the key from the ignition and engage
the parking brake of the tractor.
Set the dosing setting for your spreading work.
see instructions in paragraph »Finding the correct setting for
your spreading work« on page 77.
Fit the calibration container on the spreading spout.
Attach the two lock clips.
Fill the spreader up to at least half with fertiliser.
Weigh a large trough and place it under the discharging point of the
calibration container.
Start the tractor, engage the pto shaft and set a PTO shaft rpm to
540 or 620 rpm.
Open the dosing unit for 5 seconds to “flush” the calibration
container.
Switch the PTO shaft and the tractor off and remove the keys from
the ignition.
Empty the trough and place it back under the discharge point of the
calibration container.
Start the tractor, engage the PTO shaft and set it to 540 or 620 rpm.
Open the dosing unit for 1 minute.
Close the dosing after exactly 60 seconds.

NDICATION
If you set a high dosing setting or if you are using a small trough, open
the dosing unit for 30 seconds and multiply the weight of the collected
fertiliser by 2 when weighing it.
Switch the tractor and the PTO shaft off, remove the key from the
ignition and engage the parking brake of the tractor.
Weigh the trough with the fertiliser. Subtract the weight of the
empty trough from the total weight.
Compare the flowrate determined by you with the calculated value.
Set the dosing setting one “click” higher or lower if the calibration
result is lower or higher than expected.
Or calculate another dosing setting with the method described in:
paragraph »Adjusting the dosing setting« on page 95
or
paragraph »Calculating and adjusting dosing setting with fine
application« on page 87.
