4.6.1 Speed calibration
The speed calibration is the basic requirement for an exact spreading result. Fac-
tors such as tyre size, a different tractor, all-wheel drive, slippage between tyres
and ground, ground characteristics and tyre pressure influence the speed meas-
urement and therefore the spreading result.
Preparing the speed calibration:
The exact calculation of the number of speed pulses over 100 m is very important
for the precise discharge of the fertiliser quantity.
Run the calibration in the field. This reduces the influence of the ground char-
acteristics on the calibration result.
Measure a 100 m reference distance as accurately as possible.
Engage the four-wheel drive.
If possible, only fill the mineral fertiliser spreader until it is half-full.
Calling up the speed settings:
In the control unit Quantron E2 up to 4 different profiles for type and number of
pulses can be saved. You can assign names to these profiles (e. g. tractor name).
Before spreading, check that the correct profile is opened in the control unit.

1. Switch from the Hopper configuration menu to the tractor (km/h) menu.
The displayed values for name, origin and number of pulses refer to the
profile highlighted in black.
2. Press the function key ( F1-F4 ) under the saving location symbol to switch the
tractor profile.
