Abstract
A method of mountng a measuring device for measuring the relative positions of two objects, such as, the bed and the carriage of the machine, wherein a graduation of an embodiment of measure is scanned without contact by a scanning device. The embodiment of measure is initially aligned and mounted on the first of two objects. The scanning device is mounted on an auxiliary device and is exactly calibrated relative to the graduation of the embodiment of measure. The scanning device is displaced guided on the embodiment of measure by means of the auxiliary device until a stop surface of the second object is reached. The scanning device is fastened with the intermediate arrangement of an attachment device on the stop surface of the second object in such a way that the calibration of the scanning device relative to the graduation is maintained. The auxiliary device is then loosened and removed from the scanning device.
