e.g. The configured measurement range is 0...20m and the actual measured distance is 14m. This results in
a measurement uncertainty of ± 0.2m (1% of 20m), which includes all parameters (temperature drift,
sensor accuracy, linearity, target color etc.). The uncertainty decreases, if the ambient temperature is
stable.
