Problems solved by technology

[0007] At present, during the verification and calibration of electronic desk scales, the weights are manually placed on the carrier. During the verification and calibration of batch electronic scales, the loading and unloading of standard weights must be repeated, which is a lot of manpower consumption. At the same time The operation process also has a great influence on the accuracy of the standard weight, especially for the verification and calibration of large-scale electronic scales, the loading and unloading of large-mass weights will bring greater trouble to the verification and calibration process, and at the same time seriously reduce the verification. Efficiency, human operation also has a great influence on the accuracy of standard weights
