Abstract: A method is provided for measuring an energy efficiency of a quantitative weighing device. A data measurement part is formed by: recording a control time of fast charging, recording a control time of slow charging, recording a comparison prohibition time, and recording weighing data. A current device reliability parameter, a fast charging feed flow, and a slow charging feed flow are calculated, based on the comparison prohibition time and the control time of slow charging. The fastest feed time under a requirement of a target reliability parameter is calculated as the difference between the target reliability parameter and the calculated control reliability parameter. By using the method, application data, such as capability of a quantitative control device and energy efficiency of the quantitative weighing device, can be intuitively obtained. This facilitates commissioning, maintenance, and use of the quantitative weighing control device.
