Abstract
A method for configuring a calibration mechanism in a force sensor (100) has the steps of: coupling an end of the calibration lever (1071) to a loading end (102) of the force sensor; adjusting, in a no-load condition, the center of gravity (G0) of the unloaded calibration lever (1071), so that the center of gravity (G0) lies on a horizontal line (H) through the center of a calibration lever fulcrum (1031) at a fixed end (103) thereof; and adjusting, in a full-load condition, the center of gravity (G1) of the calibration lever (1071) loaded with the calibration weight (106), so that the center of gravity (G1) lies on the horizontal line (H) through the center of the calibration lever fulcrum. The calibration error caused by inclination in the force sensor is reduced by practice of this method.
