实验室在对电子天平定期进行检定或校准的基础上,还必须做好电子天平的期间核查,尤其是对使用频率较高、环境变化较多的电子天平,以确保检查数据的稳定度和准确度。一、核查规则以JJG1036-2008《电子天平检定规程》、JJG99-2006《砝码检定规程》为依据,以《电子天平内校规程》、电子天平说明书为指导,对实验室I级电子天平进行期间核查。核查频率视电子天平的使用频率和工作环境而定,在电子天平两次
On the basis of regularly checking or calibrating the electronic balance, the laboratory must also check the period of the electronic balance, especially for electronic balances with high frequency of use and environmental changes so as to ensure the stability and accuracy of the inspection data degree. First, the verification rules to JJG1036-2008 “electronic balance verification procedures”, JJG99-2006 “weight verification procedures” as the basis, “Electronic Scale Internal Order”, electronic balance manual as a guide, the laboratory I-scale electronic balance During verification. The frequency of verification depends on the frequency and working environment of the electronic balance, on the electronic balance twice
