Speed calibration
The speed transducer can be calibrated theoretically or practically.
The practical method is recommended.
Speed constant
The theoretical speed constant, units per pulse (UPP), is the distance in metre
on the circumference of the wheel between magnets.
For example, if the wheel circumference is 2.00 m and
4 magnets are fitted, UPP is 0.5000.
Speed practical
Practical calibration of speed is done by driving a measured distance and cor-
recting the display so that the actual and the calculated
distances are the same.
Theoretical speed calibration should be carried out before practical speed
calibration.
Calibration should take place in the field with a half full tank and normal working
tyre pressure in order to obtain the wheel’s real “working radius”.
