DEVICE WITH COMPLEXED CARRIERS OF EVEN ANGULAR SCALES OF DIFFERENT DISCRECITY FOR CALIBRATION OF ANGLE-SETTING AND ANGLE-MEASURING INSTRUMENTS Russian patent published in 2013 - IPC G01C25/00 

FIELD: instrument making.

SUBSTANCE: device for calibration of angle-setting and angle-measuring instruments in fixed graduation marks, comprising a rotary mechanism installed on a fixed base, where a rotary carrier of a discrete even angular scale of full range of 360° is installed, having a structural capability to transfer its rotation to a rotary part of the calibrated instrument, and also a facility to fix any of the specified graduation marks as it rotates, at the same time the body of the calibrated instrument and the facility of fixation are motionless and are installed on the same base, differing by the fact that the device is equipped with at least one additional carrier of similar scale and the appropriate facility for fixation of its marks, and carriers of all scales are installed coaxially and connected into a single rotary unit, at the same time the number of graduation marks of any carrier is not a divider of the graduation marks number in another carrier, and facilities of graduation marks fixation may be both individual for each carrier and complexed into one common or several group facilities of fixation.

EFFECT: achievement of consistent improvement of resource and metrological indices of calibration due to complexing of two and more independent carriers of reference discrete even angular scales.
