Title: Electronic balance
Inventor: NISHIO AKIRA
IPC: G01G23/01
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To simplify sensitivity check and sensitivity calibration operations and prevent sensitivity calibration errors due to drift of metering value using a weight load by adopting the metering value sampled according to the command from a commanding means. SOLUTION: Sensitivity checking operation is performed through an instruction from a commanding means a. Namely, a metering value moc is sampled in a no-load state, and further a metering value mFC is is sampled after loading a weight C of known mass, then a sensitivity error quantity ΔW is calculated by using the value and is indicated. Furthermore, the sensitivity error quantity ΔW or the metering values moc and MFC sampled in advance in the no-load state and weight loading state are used as they are to calibrate the sensitivity and update a span factor α. Therefore, the sensitivity check and sensitivity calibration are both performed by only one loading/unloading of a weight.  In addition, since a new span factor α<-> is calculated by using the metering values moc and mFC sampled by one loading of a weight, no error due to drift of the metering value through weight loading is generated.
