The testbed executes the calibration of taximeters, odometer and speed measurement and speed display devices on cars / vans with roller dynamometer test benches for distance and speed measurements.

The wheels of the vehicles are moved by electric motor driven rollers. The speed or the distance is displayed on a large screen. With each increase in the increment of the taximeter, the driven distance is measured. The measured distance must correspond precisely with the legal requirements

The speed and the distance of the precisely calibrated roller is determined very accurately by an incremental-encoder with high resolution and displayed. A comparison with the speedometer of the vehicle, or the taximeter immediately displays the deviations. If the values are outside specified limits, the color of the display is changed. In addition, error logs can be printed immediately.
