Étape 10
Switch on your multimeter, and set the dial to DC voltage mode (indicated by a V with a straight line, or the symbol ⎓). Virtually all consumer electronic devices run on DC voltage. AC voltage—the kind that runs through the lines to your house—is considerably more dangerous, and beyond the scope of this guide.
  • Switch on your multimeter, and set the dial to DC voltage mode (indicated by a V with a straight line, or the symbol ⎓).

  • Virtually all consumer electronic devices run on DC voltage. AC voltage—the kind that runs through the lines to your house—is considerably more dangerous, and beyond the scope of this guide.

  • Most multimeters are not autoranging, meaning you will need to set the correct range for the voltage you expect to measure.

  • Each setting on the dial lists the maximum voltage it can measure. So for example, if you expect to measure more than 2 volts but less than 20, use the 20 volt setting.

  • If you're not sure, start with the highest setting.

打开您的万用表,然后将拨盘拨至直流电压档(图标为带下划线的V,或者为符号 ⎓)

一般来说所有的市售电子设备都由直流电驱动运行。交流电——就是那种经过输电线路至您家中的——因为比直流电更危险,故不在本文讨论范围中

大部分的万用表都不会自动调整量程,这意味着您需要将量程设置为适合您要测试的电压范围中

量程的每个档位都有其能测试的最大电压。举例来说,如果您需要测试的电压大于2伏特并且小于20伏特,就选择20伏特的量程档位

如果您不确定,请使用万用表的最大量程测试
