A manual, high-precision measurement of changes in inclination on structures and surfaces (e.g. rock surface) is preferably carried out with the Clinometer BL 200, which has a base length of 200 mm, or the Clinometer BL1000 with a base length of 1000 mm. Setting points are mounted in the structure or on the rock face to carry out inclination measurements with the portable clinometer. The system has a measuring accuracy of +/-0.003 mm/m and a measuring range of +/-1°.
