This small resistance is normally measured with a DMM or a micro - ohmmeter.
这个小的电阻值通常用数字多用表或者微欧姆计来测量。
A typical lifetime test system includes a communication analyzer, power supplies, a handset controller, audio test instruments, and a DMM.
典型的寿命测试系统包括一台通信分析仪、电源、一个手机控制器、音频测试仪器和一台数字多用表（DMM）。
Given these DMM characteristics, it's not possible to use a DMM to measure signals at levels close to theoretical measurement limits, as shown in Figure 1-3.
数字多用表的技术特性决定了其不可能测量接近理论极限的信号，如图1 - 3所示。
It doesn't have the internal resistors (rs), as in the DMM, so all four leads must be connected to make a measurement.
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。
However, the traditional measuring instruments such as DSO, DMM, Logic Analyzer have only focus on a certain number of signal or electrical parameters.
然而，传统的测量仪器如示波器，万用表，逻辑分析仪等都只是针对某一些信号或者电参数的测量。
Experiments were carried out on a S1100A2 single cylinder diesel engine, with three kind of oxygenated additive-ethanol, DMM, and DMC added in to diesel oil.
在一台S1100A2型单缸柴油机上，通过在柴油中添加乙醇、甲缩醛（DMM）、碳酸二甲脂（DMC）等三种含氧添加剂，研究了在常用工况下混合燃料的含氧量对柴油机排放特性的影响。
