这个小的电阻值通常用数字多用表或者微欧姆计来测量。
This small resistance is normally measured with a DMM or a micro - ohmmeter.
微欧姆计和很多数字多用表使用的另一种消除偏置的方法是偏置补偿欧姆法。
Another offset-canceling method used by micro-ohmmeters and many DMMs is the offset-compensated ohms method.
对于大多数的应用来说，微欧姆计或数字多用表足以用来进行接触电阻的测量工作。
For most applications, the micro-ohmmeter or DMM is sufficient for contact resistance measurements.
图1 - 24所示的脉冲驱动模式使微欧姆计能够消除被测未知电阻上的寄生偏置电压。
The pulsed drive mode, shown in Figure 1-24, allows the micro - ohmmeter to cancel stray offset voltages in the unknown resistance being measured.
与数字多用表不同，微欧姆计没有内部电阻器(RS)，所以四条引线都要连接才能进行测量。
It doesn't have the internal resistors (rs), as in the DMM, so all four leads must be connected to make a measurement.
