METHOD TO ADJUST SENSITIVITY AXIS POSITION IN PENDULUM-TYPE COMPENSATING ACCELEROMETER Russian patent published in 2008 - IPC G01P15/00 

FIELD: instrument making.

SUBSTANCE: method to adjust the sensitivity axis position in pendulum-type compensating accelerometer with a photoelectrical angle pickup consists in selecting the position of its components and measuring the output signal. Here note that the accelerometer is arranged with its pendulum down, a signal of the two photo receivers arranged nearby of the modulator arm, the accelerometer is turned around the axis of rotation of the moving system and set to the position wherein the said signal is zero. The output signal of the photo receivers pair arranged nearby the arm of the other modulator, this pair is moved along the direction the modulator moves till the position wherein their output signal makes zero and the photo receivers are fixed at this position.

EFFECT: higher accuracy.
