为了开展电工特种测试仪器的行业计量服务工作,机电部于1992年12月组织专家评审组,对上海电动工具研究所申请建立部级专业计量中心站进行了全面考核,评审合格,并于1993年3月下达机电科[1993]335号文,正式批准为机械电子工业部第十专业计量中心站。机械电子工业部第十专业计量中心站可开展的检定测试项目有: 1.四探针电阻率测试仪检定装置,可开展电阻率范围为10~(-4)Ωcm～10~3Ωcm,准确度等级为±3.0级以下四探针测试仪的检定。
In order to carry out the electrician special testing equipment industry metrology service, the Electrical and Mechanical Services Department in December 1992 organized an expert review team to apply for the establishment of ministerial-level professional metrology center in Shanghai Electric Tools Research Institute conducted a comprehensive assessment, assessment of qualified and in 1993 March Electromechanical issued [1993] No. 335, formally approved the Ministry of Machinery and Electronic Industry tenth professional metering center station. The tenth professional metrology center of the Ministry of Machinery and Electronic Industry can carry out the verification test items: 1. Four-probe resistivity tester verification device can carry out the resistivity range of 10 ~ (-4) Ωcm ~ 10 ~ 3Ωcm, accuracy Level of ± 3.0 following the four-probe tester test.
