ABSTRACT:
An electronic stereo clino-compass which can be targeted directly at the discontinuous surface of a soil layer and in particular, where the running direction (azimuth) and inclination of a target surface can be measured quickly and easily without the necessity of specialized knowledge. The electronic stereo clino-meter includes a three axis inclination angle sensor for outputting an electrical signal taken as a measurement of an inclination angle, a three-axis azimuth angle sensor for outputting an electrical signal taken as a measurement of an azimuth angle taking the geomagnetic field as a basis, an analogue-to-digital converter for outputting digital signals converted from electrical signals outputted from each of the sensors, an arithmetic unit for providing an output from a calculation process carried out on the inclination angle and azimuth angle signals based on the output from the analogue-to-digital converter, a display conversion unit for converting electrical signals from the control unit or the memory unit in conformity with a predetermined display technique, and a display unit for displaying values converted by the display conversion unit.
