电子天平检定的条件、项目和方法

Conditions, Items and Methods of Electronic Balance Verification

电子天平的检定条件有对标准砝码的要求，有与电子天平检定相关的器具，有检定所需的环境条件，以及检定前天平的清洁处理与存放时间要求。电子天平的检定方法有电子天平鉴别力的检定，灵敏度的检定，各载荷点的最大允许误差的检定，配衡功能的检查，抗倾斜能力的检查，以及电压和频率变化对天平影响的检验。

Verification conditions of electronic balance are the requirements to standard weight, equipments related to electronic balance verification, environmental conditions that verification required, as well as cleaning and storage requirements before the balance verification. Verification methods of electronic balance includes discriminability test, sensitivity test, maximum permissible error of each load point, the check of tared function, the check of anti-tih capability, as well as the influence of voltage and frequency variations on the balance.
