一种高精度交流电桥自动辅助平衡方法
An Auto Source Balance Method of High Precision AC Bridge
摘要
Abstract
An auto auxiliary source balance method is proposed and achieved. The impact of this method on the measurement accuracy ofthe auto source balance circuit is negligible. And the method can greatly improve the convergence speed of the AC bridge′s balance procedure A high precision coaxial AC bridge is constructed at NIM for high precision capacitance transmissiononly by the auto source balance method. The bridge can transmit capacitance with an uncertainty of 3×10-8 (k=1) at 1592Hz.关键词
