High resistance measurements using the constant-current method may be made using either an electrometer voltmeter and current source or just an electrometer ohmmeter.
采用恒流法，可以使用静电计电压表和电流源或者只使用静电计欧姆计来测量高电阻。
As with the four-point collinear probe method, a differential measurement may be required if the sample resistance is of the same magnitude as the isolation (meter common to ground) of the voltmeter.
与四点同线探针法一样，如果样品电阻和电压表的绝缘电阻（电压表的公共端到地）是同一数量级的，就可能需要使用差分测量。
