Notes on correction value determination
There are three steps involved in calculating a correction
value:
•
Measuring wheel circumference on the road
•
Measuring wheel circumference on the rolling road
Set the CTC II correction value here to + 0.0 %.
•
Calculating the correction value:
R
s
= determined wheel circumference on the road
R
r
= determined wheel circumference on the rolling road
K = correction value
K = ((R
s
- R
r
) / R
s
) * 100%
The determined correction value is vehicle-specific and rolling
road-specific; it must be entered before every automatic
measuring procedure.
