7.2 TECHNICAL FEATURES
7.2.1 Accuracy of measurements
The accuracy of measures in laboratory is more than 98 %-. This accuracy is only reached for the best
distance of measurement (60 to 80 m for cars and more for trucks).
7.2.2 Range of speed to be detected
The range of speed to be detected runs from 5 to +/- 250 km/h. It is possible to define a speed area
for the display, by fixing minimum and maximum thresholds (see p. 22). Measurements above 5 km/h
are memorised, whatever the choice of display.
