数字多用表自动检定系统

Automatic verification system for the digital multimeter

介绍了数字多用表自动检定系统的系统配置、工作原理、软件设计,并对整套装置的不确定度进行了分析。

This paper mainly presents working principle,system software,hardware construction and specification of automated test system for the digital multimeter.Design proposal of this system software and the software of the high accuracy multimeter are in- troduced in detail,and the paper also analyzes the overall uncertainty.By using this system, a metrological department like us can use the resources more efficiently and achieve automated verification completely.
