摘　　要：本文利用HP34970A数据采集仪抗干扰能力强的特点,实现了工业热电偶、热电阻的自动检定。系统是便携式的,不但适用于实验室检定,也适于现场动态校准。开发周期短,系统功能可扩展,一般检定人员即可完成设计。系统的不确定度完全满足规程要求。In this paper, HP34970A Data Acquisition Unit has been used in auto-calibration system because of its strong ability of anti-interference. It is a portable system, can be used not only in laboratory but also in site. The development cycle is short and the function is expansion, normal personnel can do it. The system uncertainty satisfied the requirement of calibration rules.
