Abstract
A driving arrangement is provided for a measuring instrument having a movable element which is movable relative to a measuring instrument body. Measurement of an object to be measured is carried out through movement of the movable element. A driving and guide device is mounted on the measuring instrument body, and includes a driving cylinder having a piston received therein for axial movement. The movable element is moved in synchronism with the axial movement of the piston. A hydraulic fluid control device is arranged at a location remote from the measuring instrument body, for supplying hydraulic fluid to the driving cylinder of the driving and guide device to cause the axial movement of the piston of the driving cylinder.
