Abstract： This article combines national regulatory requirements and practical work experience to sort out the precautions in the calibration process of electronic scales， and takes the uncertainty evaluation of the measurement results of a 210 g/0.01 mg electronic balance as an example to explore. It further guides metrological calibration personnel to pay attention to possible problems in the calibration process， strictly follow metrological calibration regulations， and combine the comprehensive performance of electronic scales for calibration work.

Keywords： electronic balance；verification；uncertainty
