摘　要:為了實現(xiàn)對高阻計靜電計準確、可靠的校準／檢定，特建立高阻計，靜電計檢定裝置。該檢定裝置由KEITHLEY 263校準儀，源組成，采用直接測量法進行校準，檢定工作。通過對其測量不確定度進行詳細評定，證明高阻計，靜電計檢定裝置可圓滿地實現(xiàn)對KEITHLEY 6517A等高精密靜電計，高阻計的校準／檢定，從而大大增強了電磁學計量領域高值電阻和微電流等參數(shù)的測試能力。[著者文摘]


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]
