Abstract
An electronic scale calibrating method for an electronic scale is provided. The electronic scale includes a weighing pan, a memory unit, a first weight sensor and a second weight sensor. The weighing pan has a placement region. The first weight sensor and the second weight sensor are symmetric with respect to the placement region. Firstly, two standard samples are placed in the placement region simultaneously. Then, the first weight sensor and the second weight sensor sense the two standard samples to obtain a first read value and a second read value, respectively. Then, a first parameter, a second parameter, a first calibration coefficient and a second calibration coefficient are defined according to the first read value and the second read value. Then, a calibration formula is generated and stored in the memory unit.
