多功能过程校验仪的检定及问题探讨

Discussion on Calibration and Problems of Multifunction Process Calibrators

多功能过程校验仪越来越多地应用于现场校验,为现场检修维护人员提供了方便。由于在检定过程中的一些认识上的问题,计量人员在检定过程中往往不能选择合适的标准仪器,本文通过对多功能过程校验仪检定过程中出现的问题进行分析,提出了检定过程中标准仪器选择和使用的一些看法,并对热电偶输出与测量功能的检定提出了一些建议。

Multifunction process calibrators are more and more applied to on-site verification and calibration, facilitating the on-site mainte-nance. Because of some problems in the process of calibration, measurement operators are often unable to select appropriate instruments. This pa-per presents some ideas on the selection and use of the standard instruments in the calibration process, and proposes some suggestions on thermo-couple outputs and verification of measurement functions.
