| Abstract | This paper presents a method to ameliorate the resolution of an electronic inclinometer Nivel20 which has resolution one micro-radians (? 0.0000573 degrees) with the addition of the measuring position for the average of repeated measurements. Using the piezoelectric to achieve a change in slope that is lower than its resolution. Capacitive sensor is used to measure the first step distance for the compensation system and system design software is used for automatic movement in the experiment. The results show that before the compensation, the accuracy at each measurement position is ?2.5 micro-radians and after the compensation, the accuracy is ?0.15 micro-radians that is smaller than its resolution three times. |
