摘要：An electronic balance includes a sample plate for placing a sample, a loaddetecting unit for determining a weight of the sample, a sensitivity calibration mechanismhaving a calibration weight disposed under the sample plate for applying a load of thecalibration weight to the load detecting unit, a weight holding member with a spring
property for holding the calibration weight when the load of the calibration weight is notapplied to the load detecting unit, and a pressing member disposed above the weightholding member for restricting an upper movement of the weight holding member. Theload detecting unit converts a load of the sample placed on the sample plate into anelectrical signal according to a sensitivity coefficient to determine the weight of thesample. The sensitivity coefficient is calibrated when the load of the calibration weight isapplied to the load detecting unit.
