ABSTRACT:
This invention relates to a method and an apparatus for calibrating length indicators (dial indicators). The length indicators are secured in a stand and brought into contact with a number of feeler gauges adhered together into a connective sequence, which are fed in steps under the dial indicator in contact with the measuring point of the latter. According to the invention these feeler gauges preferably adhered to a reference plane with a circular surface extent in the horizontal plane. The reference plane is rotatably mounted in the same stand as the dial indicator and is rotatable under the same.
