ABSTRACT:
A method is disclosed for the correction of errors in the measurement of caster, king-pin-inclination and camber on motor vehicles. Inclinometers are used whereby errors are avoided of the type caused by non-horizontal positioning of the vehicle under test. Measurements on the vehicle can easily be carried out without special loading-weights and without roping the vehicle down to the ground. The additional angles of error caused by the inclined position of the vehicle with respect to the horizontal are measured and combined as a correction factor with the measured geometrical values.
