Description

technical field [0001] The invention relates to the technical field of digital instruments, in particular to an intelligent verification system and method for multi-table digital instruments. Background technique [0002] The verification work of devices and digital meters is a very important link in the management of electric power production, and it is also one of the important means to ensure the accuracy of electric power data. Many, complex ranges, high data accuracy requirements, and long effective data bits are the reasons. The manual operation in the prior art has a large workload and low work efficiency, and one person can only calibrate one multimeter at a time, and cannot calibrate multiple meters at the same time. ; And due to the different technical levels of the testers, it is very easy to cause measurement errors, and it is not conducive to the realization of comprehensive quality management. Contents of the invention [0003] In order to solve the problem ...
