FIELD: instrument engineering.
SUBSTANCE: invention relates to micromechanical sensors of rotation speed using the Coriolis effect, in particular to micromechanical gyroscopes (MMG) of vibration type. Method of adjusting phase of reference signal of demodulator output tract of micromechanical gyroscope consists in measurement of output signal at changing the phase of the reference signal and subsequent analysis of the obtained relationship which the successively set first and second value of angular velocity along the axis of sensitivity of the micromechanical gyroscope, dependences of output signal are determined from phase for two values of specified angular speed, the first (φ1) and second (φ2) value of phase are calculated corresponding to the intersection points of found dependencies of output signal on phase and phase of reference signal equal to value of 0.5 (φ1+φ2) is selected.
EFFECT: higher accuracy of MMG.
