Permissible error limits
Distance
Permissible error limit of the distance measurement (on a distance
of at least 1000 m):
•
±
1 % before installation
•
±
2 % during installation and during the regularly inspections
•
±
4 % during operation
Accuracy (resolution) of the distance measurement:
•
at least 0,1 km
Speed
In order to achieve a permissible error limit of the displayed speed
during operation of
±
6 km/h, the following influences must be con-
sidered:
•
Error limit of
±
2 km/h for input deviations (such as tire devia-
tions)
•
Error limit of
±
1 km/h during installation measurements or regu-
larly inspections
From this results the permissible error limit of the speed meas-
urement (with speed between 20 and 180 km/h, characteristic coef-
ficient of the vehicle between 4000 and 25000 pulses/km):
•
±
1 km/h
Accuracy of the speed measurement:
•
at least 1 km/h
Due to the data storage resolution, there is another permissible error
limit of
±
0.5 km/h for the speed saved by the recording equipment.
