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.

要确保输入端钳位电压足够的高，以避免由于源接点的非线性而产生的问题。

Make sure the compliance voltage is high enough to avoid problems due to source contact non-linearity.

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.
