Calibrating the speed sensor with the 100m method
 
When calibrating the speed sensor with the 100m method, you determine the number of impulses received by the speed sensor in a distance of 100m. When you know the amount of impulses, the job computer can calculate the current speed.
 
 
If you know the number of impulses for the wheel sensor, you can also enter this number manually.
 
 
You can enter different pulse values for up to three different wheels.
 
 
 
Procedure
 
 
 
þ
Wheel sensor, radar sensor or GPS speed sensor is installed on the implement.
þ
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.
þ
The tractor with connected implement is ready for a 100m drive and is at the start of the marked distance.
1.
Ensure that all prerequisites have been fulfilled.
2.
Switch to the “CALIBRATION – wheel impulses” screen:
 FS_JR3_Einstellungn-Menü >  FS_JR3_Geschwindigkeit-Einstellungen >  FS_JR3_Geschwindigkeit-kalibrierung
3.
 FS_JR3_START - Start calibration.
The following function icons appear:
 FS_JR3_OK - Stop calibration.
 FS_JR3_Abbruch - Abort calibration.
4.
Drive the previously measured 100m distance and stop at the end.
During the drive, the currently determined impulses are displayed.
5.
 FS_JR3_OK - Stop calibration.
6.
 FS_JR3_Zurück einfach - Exit the screen.
The number of impulses appears on the “Wheel impulses” line
