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。
Thermocouples and thermopiles are devices that use the Seebeck effect to measure the temperature difference between two objects, one connected to a voltmeter and the other to the probe.
热电偶以及热电堆也是利用塞贝克效应的器件用于测试两个待测点之间的温度差,其工作时将其中的一个待测点连接伏特表而另一个待测点连接传感器探头。
The temperature of the voltmeter, and hence that of the material being measured by the probe, can be measured separately using cold junction compensation techniques.
利用冷接点补偿技术,伏特表的温度以及传感器探头反馈的温度可以被分别测量。
