A position measuring system includes a first portion and a second portion, which can be moved relative to the first portion. The first portion has a material measure having a multiplicity of markings that are each able to assume two different values. A number m of directly successive markings codes a respective explicit absolute position along the material measure, and a number m−1 of directly successive markings does not code an explicit absolute position. The second portion has a scanning device having a number k of individual sensors for scanning a number n of directly successive markings. The scanning device is functionally connected to an evaluation device in order to ascertain the position of the second portion relative to the first portion. The condition n>m is satisfied, and the evaluation device is configured to recognize a scanning error in the scanning device. |
