A device and a method for mechanically adjusting graduation-scale carrier members, which form a scale for a preferably incremental measuring system. The device and the method can be used both for angle measuring instruments as well as for length measuring instruments. A wedge-shaped form-locking between segments of the graduation-scale carrier members and fixing elements enables forces produced by setting screws orthogonally to the measuring direction and exerted on the fixing elements to be varied in their effective direction, so that they have a component that is parallel to the measuring direction and, thus, to the extension of the graduation-scale carrier member. As a result, the setting screws can be used to exert a compressive or tensile force on the graduation-scale carrier member to be used for the adjustment thereof. The gap width at the joint of two graduation-scale carrier members can be adjusted in the same way as is the graduation-scale carrier member. The wedge-shaped segments arranged on the graduation-scale carrier members and the wedge-shaped fixing elements cause the forces exerted on the fixing elements by setting screws to be diverted in the measuring direction at the graduation-scale carrier members and, in such a way, that the gap width of the joint is adjusted.
