Abstract
A method of measuring radial and/or lateral run-out of a rotary member, where the rotary member is mounted in a testing machine by a play-compensating clamping arrangement, and rotated. While it rotates the rotary member is sensed in the region of its peripheral and/or lateral surfaces and the result of the sensing operation is used to produce run-out diagrams. First and second run-out diagrams which are turned relative to each other through 180.degree. with respect to the clamping mounting arrangement are combined together, thereby to compensate in the combination diagram for the geometrical measurement errors resulting from the clamping mounting arrangement in the initial diagrams.
