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。
Another consideration when measuring voltages from high resistance sources is the input bias current of the voltmeter.
如果使用分离的电流源和电压表来进行低电阻测量，则必须检查每台仪器的非欧姆接触情况。
If using a separate current source and voltmeter to make low resistance measurements, each instrument must be checked for non-ohmic contacts.
所以需要使用具有高输入电阻的电压表，例如静电计。
Therefore, a voltmeter with high input resistance, such as an electrometer, is required.
