Auto-ranging voltage measurement

If your multimeter is manual ranging, skip to the next step.
Place the red probe on the positive terminal, and the black probe on the negative terminal. The multimeter will display the measured voltage.
Reversing the probes won't do any harm; it just gives a negative reading.
Skip the next step, which describes how to measure voltage using manual ranging multimeters.

自动量程电压测量

如果万用表是手动量程，请跳至下一步。
将红色探针放在正极端子上，将黑色探针放在负极端子上。万用表将显示测量的电压。
反转探头不会造成任何伤害；它只是提供一个负的读数。
跳过下一步，该步骤介绍如何使用手动量程万用表测量电压。
