Run all ground wires to a common ground point.
把所有地线连到一公共的接地点。
In this paper, it exploit the method based on common ground point fold step by step to strike a more accurate conversion of wave static correction by iteration.
本文利用共地面点叠加法，通过迭代的方式逐步求取较为准确的转换波的静校正量。
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。
