如图2 - 2所示,输入偏置电流(IBIAS)在源电阻(RS)上产生了误差电压。
Another consideration when measuring voltages from high resistance sources is the input bias current of the voltmeter.在测量高电阻源时要考虑的另一个问题是电压表的输入偏置电流。
The input bias current flows at the instrument input due to internal instrument circuitry and the internal bias voltage.仪器内部电路和内部的偏移电压会在仪器的输入端引起输入偏置电流。
