Another consideration when measuring voltages from high resistance sources is the inputbiascurrent 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。
2
The inputbiascurrent 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。

Although inputbiascurrent is a common source of this type of error, currents generated by external circuits can also result in errors due to voltage drops across the source resistance.
