Calibrating the wheel sensor
▪
When you have fitted a wheel sensor (Sensor X) on the wheel of the tractor.
▪
Before the first start-up.
▪
After changing tires.
▪
After tractor change (if the wheel sensor was fitted to the tractor's wheel).
▪
When the speed shown on the work screen is incorrect.
▪
When the traveled route shown on the work screen is incorrect.
NOTICE
Imprecise calibration
The speed cannot be precisely determined with an incorrectly calibrated wheel sensor.
As a result all the calculations of the area sprayed, the route traveled and the volume applied will be
highly imprecise.
◦
Calibrate the wheel sensor very precisely.
Determining pulses per 100 meters
When calibrating the wheel sensor with the 100m method, you determine the number of pulses
received by the sensor in a distance of 100m.
In order for the system to function correctly, the wheel sensor must receive at least 250 pulses over a
distance of 100 meters.
To increase the number of pulses, you must mount additional magnets opposite of the wheel sensor.
If you know the number of pulses for the wheel sensor you can enter this number manually as well.
Wheel sensor is mounted.
All wheel sensor magnets are fully functional.
A distance of 100m has been measured and marked. The distance must correspond to the field
conditions. It should therefore lead over a meadow or a field.
The tractor with connected machine is operational for a 100m drive and is at the start of the
marked distance.
