php editor Xiaoxin will introduce to you how to test the multimeter test method of 220V voltage. In daily life, we often need to test the voltage of electrical equipment, and a multimeter is a very convenient tool. The method of testing 220V voltage is very simple. You only need to connect the red test pen to the live wire of the appliance, connect the black test pen to the neutral line of the appliance, and then turn on the voltage range of the multimeter to read the voltage of the appliance. voltage value. When using a multimeter to test voltage, pay attention to safety to ensure you do not get an electric shock.
1. First, we need to open the multimeter. After opening it, we insert the black test lead into the COM port and insert the red Insert the test lead into the VΩ port;
2. Then we turn the rotation gear to the AC gear 750V, and then the voltage will be displayed on the LCD screen;
3. After the final measurement, turn the gear to OFF. Under normal circumstances, with a voltage of 220V, the number on the display should be about 218-239V;
The above is the detailed content of How to test 220 voltage with multimeter. For more information, please follow other related articles on the PHP Chinese website!
