测量电桥的误差分析

Analysis of the Error of Measurement Bridge

分析了测量电桥中桥臂参数选择引起的误差、零位误差、引线电阻误差及非线性误差，并提出了调整、消除及处理方法，力求把测量误差减少到最小范围，以提高测量的精度．

Bystuding the error of measurement bridge, this article amalyses the parameter of bridge arm, null-selling errov, the resistence enor of lead and non-linear error, and accordingly some methods of adjustment, remarement and settlement are provided to reduce the measurement trror to the minimum, and there fore to raise the precison of measurement.
