THE UNCERTAINTY ANALYSIS OF MEASURING INNER- RESISTANCE OF MICRO - AMPERE - METER WITH THE SUBSTITUTE METHODWang Jiyou ,Yuan Anjuan Beijing University of Technology, Beijing, 100022Abstract:Among the methods of measuring inner - resistance of micro - ampere - meter with the substitute method is the most simple one. In this paper, the parameters of affecting the uncertainty of the measured result are analyzed. The best conditions of the measurement are obtained. The uncertainty of the measured result is caculated in general laboratory.[著者文摘]
