3.1.1.1
CONSTANT
The theoretical speed constant, pulses per unit (PPU), is the distance in
metre on the circumference of the wheel between protrusion (or magnets).
E.g. If the wheel circumference is 2.00 m with 4 protrusions, PPU is 0.5000.

SPRAYER
Practical
Practical calibration of speed is done by driving a measured distance and
correcting the display so that the actual and the calculated
distances are the same.
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".
Method
1. Measure a distance not less than 75 metres.
2. Park the tractor at the start of the measured distance.
3. Press . When zero distance [ 0 m ] shows, drive the distance.
