The apparatus has a plate (1) pivotingly mounted on a horizontal axis (X-X') with stops (4) limiting the inclination of the plate (1) on either side of the axis, means for measuring (7) the inclination of the plate, means for recording (14) values provided by said measuring means (7), and means for displaying (17) values recorded in said recording means (14). The stops (4) are adjustable. The measuring means consist of an electric potentiometer (7) servocontrolled by the motion of the plate (1) about its pivoting axis (X-X') and associated with an electric voltage or current measuring apparatus of which the output is connected to an analog-digital converter (10) of which the output is connected to the input (12) of a first digital data memory (14).
