Establishment and uncertainty evaluation of high resistance meter/electrometer verification equipmentWANG Xiao-min Metrology and Testing Center,China Academy of Engineering Physics,Mianyang 621900,ChinaAbstract:The high resistance meter ＆ electrometer verification equipment was set up in order to achieve accurate and reliable calibration and verification of high resistance meter ＆ electrometer. The high resistance meter ＆ electrometer verification equipment was formed by the KEITHLEY 263 Calibrator ＆ Source. The calibration ＆ verification work used the method of direct measurement. The accurate evaluation of uncertainty indicated that the high resistance meter ＆ electrometer verification equipment could achieve accurate calibration ＆ verification for KEITHLEY6517A, etc. This greatly increased the test ability of high-value resistors and micro-current in the electromagnetic measurement fields.[著者文摘]
