Abstract:
A method for assembling a position measuring device, in which a scanning element is fastened to a first object, and a scale comprising a measurement division is fastened to a further object, a fastening between the scale and the further object being done while maintaining a predetermined scanning distance between the measurement division and the scanning element, wherein the scanning distance is set by:positioning the scanning element at a first reference position relative to the scale; positioning a first part and a second part of a positioning device at a second reference position; fixing the first part of the positioning device directly or indirectly to the scale; fixing the second part of the positioning device directly or indirectly to the scanning element in a direction of motion along the scanning distance; and moving the first part of the positioning device relative to the second part of the positioning device by a predetermined distance in a direction of the scanning distance so that the scanning element is put into a second reference position relative to the scale, in which position a requisite scanning distance is accomplished.
