FIELD: measuring equipment.
SUBSTANCE: invention relates to measurement equipment, in particular for measurement of relative location of planes and external spherical surface. Basing element containing base prisms is placed on the mounting plane. Main reading device is installed on basing element to provide preset projection to measuring probe. Object of measurement is installed by cylindrical surfaces on base prisms. Measurement object is shifted to the measuring probe of the main reading device, thus providing contact to the touch probe with the measured plane and subsequent interference. Additional reading device is mounted on the orienting prism. Measuring object is oriented by feeding orienting prism thereto. First and second readings are taken respectively on the main and additional counting devices. Readings indicate deviations from the set value of the distance from each of the measured planes to the center of the external spherical surface, and by their semi-difference – deviation from symmetry of these planes relative to the said center.
EFFECT: technical result is higher efficiency of measurements.
