Ranging accuracy

The figure below illustrates how range accuracy is defined over distance.

Figure 16. Ranging accuracy vs. distance

The ranging accuracy is a direct evaluation of the measurement error, including offset errors and output noise.

At least 90% of the ranging values are within the declared ranges. This quality indicator includes measure-to-

measure and part-to-part dispersion.
