Abstract
A gradient indicator has a clinometer arranged on a motor-driven turntable allows reversible measurements to be taken and supports the gradient indicator in precisely reproducible positions on bearing faces of the base in the various measurement positions. In addition, the turntable can tilt by a precisely defined angle in the direction of two diametrically opposed calibration axes. Movement of the turntable and evaluation of the measurement results are ensured by a microprocessor. Successive reversible measurements in the measurement and calibration axes allow automatic sensing of measurement values to be obtained with high and constant measurement precision, large measurement range and automatic calibration of the zero-point, scaling factor and gravity g.
