Abstract
This paper describes the compensation methods of a commercial capacitive-based electronic clinometer for precision measurement of inclination with an accuracy of 0.007°. To measure the inclination more precisely and quickly, the linearity error of the sensor output was compensated based on the inclination angle and sensor output curve. It was confirmed that the residual linearity error after a third-order fitting was less than 0.007°. A compensation method, which is referred to as the delay time method for shortening the stabilization time of the sensor was also discussed. Experimental results have shown the possibility of reducing the linearity error and achieving the quick measurement with the delay time method.
