在近年的电子汽车衡的使用中发现,虽然其一般故障少于机械式地中衡,但是一旦出现故障就是大故障,将使整个系统瘫痪,而在故障中尤以电子汽车衡遇雷击最为严重。作为一种特殊产品,它的检定验收一般由计量检定机构执行,而计量检定机构在检定验收时只是执行《数字指示秤》检定规程,而检定规程只以秤量准确度检定为主, In recent years, the use of electronic truck scale found that, although its general failure is less than the mechanical balance, but once the failure is a major failure, the entire system will be paralyzed, and in particular the electronic truck scale in the worst case of lightning strikes . As a special product, its verification and acceptance is generally carried out by the metrological verification agency. However, the metrological verification agency only performs the verification procedures of “digital indicating scale” when verifying and verifying, and the verification procedure is mainly based on the verification of the weighing accuracy.
