Abstract
The invention is a contour standard, which consists of a body having a rotationally symmetrical calibration region. The rotationally symmetrical calibration region encompasses a plurality of non-cylindrical axial sections, which can be concave, convex, by forming a predefined angle as radial projection or as radial depression. The calibration region has at least one measuring section, which runs parallel to the longitudinal axis of the body and which provides for axial calibration variables, as well as radial calibration variables. These calibration variables are compared with the sensed values to the calibration of a measuring instrument and the measuring instrument is adjusted based on the basis of the determined deviation. Due to the rotationally symmetrical calibration region, the contour standard is suitable both for the calibration of touch contour measuring instruments and also for the calibration of contour measuring instruments, which measure optically.
