Tachograph programmer CD400 - User manual – V2.00 r07 (9/01/2014)
4.1.6. Odometer (only for digital tachographs).
[Under development]
Using the odometer parameter to measure the W factor does not require the workshop card.
Therefore, this function can be useful for transport companies or for the authorities.
The latest is calculated by measuring the distance driven by a vehicle when the high resolution odometer is
incremented by 5m.
Drive slowly, the CD400 will detect the Start Point
/- 5m.
Mark the Start Point on the ground.
Drive slowly, the CD400 will detect the Stop Point in
around 5m (depending on last calibration accuracy).
Measure the driven distance using a decameter and
enter the value in centimeter into the CD400.
As a result, the CD400 will display the K factor of the
tachograph, the W factor of the vehicle and the
calibration error in %.
