significantly affect the results. The measurements entered are from the RT1003 measurement
origin, to the point shown in Figure 24.
Figure 24.
Measurement point for advanced slip
Measure the distance to the non-steered axle position in each axis of the vehicle co-ordinate
frame. Select the direction from the drop-down lists and enter the distances.
Typically, the measurements should all be made to an accuracy of 10 cm. Selecting an
accuracy better than 10 cm does not improve results. Using an accuracy figure worse than
20 cm will increase the drift of the RT1003. Use the accuracy fields to select or specify the
accuracy of the measurements.
The Advanced Slip feature also requires some knowledge of the road surface. Select one of
the predefined options from the drop-down list, Normal or Low friction (ice).
For the Vertical settings, the system needs to know the position of the front axle. A position at
road height, mid-way between the wheels should be used, like for the rear axle.
Measure the distances again from the RT1003 and enter them into the cells, selecting the
appropriate directions from the drop-down lists.
