摘　　要：本文针对国内绝缘电阻测量仪检定装置现状,提出了对该装置的校准问题。基于绝缘电阻测量仪检定装置的工作原理及计量特性,从校准的准备、校准项目、校准方法及对标准器的要求展开论述,提出了高压高值电阻器及高压高值电阻箱校准项目及校准方法的异同,形成了一套科学、系统的校准方案,对提高绝缘电阻测量仪检定装置的可靠性及可操作性有积极的意义。This article introduces testing methods of measurement of insulation resistance tester judging by existing status of it in China. Based on the principle of the measurement and its metrological characteristics, the article discusses the preparation, items and methods of calibration and requests for standard device, as well as similarities and differences of calibration items and method between single-point high voltage value resistor and multipoint high voltage value resistor, forms a systematic and scientific calibration scheme. It has a positive significance for improving reliability and operability of insulation resistance tester measurement.
