万用表电压档的使用方法

万用表电压档的使用方法
English:
To use the voltage function on a multimeter, start by turning the dial to the voltage setting, which is usually denoted by the symbol "V" with a straight line above it. Next, insert the red lead into the port marked with a "V" or a "+" and the black lead into the common or "-" port. Then, touch the red probe to the positive terminal of the circuit or component you want to measure and the black probe to the negative terminal. The display will show the voltage reading in either AC or DC, depending on the setting of the multimeter. Make sure to select the appropriate AC or DC setting for the type of voltage you are measuring. Finally, always remember to set the range to a higher voltage than you expect to measure to avoid damaging the multimeter.

要使用万用表的电压功能，首先将旋钮转到电压设置，通常用带有一个上方直线的符号“V”表示。

接下来，将红色测试笔插入标有“V”或“+”的端口，将黑色测试笔插入公共端口或“-”端口。

然后，将红色探针轻轻触碰到您想要测量的电路或元件的正极端，黑色探针触碰到负极端。

显示屏将显
示交流或直流电压读数，这取决于万用表的设置。

确保选择适当的交流或直流设置，以测量所需的电压类型。

最后，始终记住将量程设置为比您预期测量的电压高，以避免损坏万用表。
