ABSTRACT:
An error correction system is disclosed which includes an error correction profile element which extends in a measuring direction inside a housing which contains a measuring scale. The disclosed error compensation system is used to compensate for guidance errors of machines or division errors of the measuring scale. The correction profile element is made as a one piece element having regions of reduced cross sectional area. The profile element is mounted to the housing by means of eccentrics which can be used to adapt the contour of the correction profile element to correspond to the error to be compensated. The error correction profile bends at the regions of reduced cross sectional area while retaining a rectilinear profile in the intermediate regions between the regions of reduced cross sectional area such that a smooth transition is provided between the intermediate regions.
