Multimeter how to measure the voltage of three-phase electricity 380V
1. Adjust the knob of the multimeter to V~ and point to 750V (this level does not have to be 750, greater than 380 can be).
2. Insert one end of the red and black stylus into the com and VΩmA sockets of the multimeter respectively, the black stylus into the com socket and the red stylus into the VΩmA socket.
3. Open the multimeter, the other end of the two stylus and the line to be measured in contact (Note: three-phase electricity between each fire wire and zero line voltage is 220V, the voltage between the two fire wire is 380V)
4. The final reading displayed on the screen is the voltage value to be measured
Multimeter, also known as multipurpose meter, multi-purpose meter, triple meter, complicated meter, etc., is an indispensable measuring instrument in power electronics and other departments, generally to measure voltage, current and resistance as the main purpose. Multimeter is divided into pointer multimeter and digital multimeter according to the display mode. It is a multifunctional, multi-range measuring instrument, generally the multimeter can measure DC current, DC voltage, AC current, AC voltage, resistance and audio level, etc. Some can also measure AC current, capacitance, inductance and some parameters of semiconductors (e.g., β) and so on.
1. Adjust the knob of the multimeter to the V ~ file, and point to 750V (this file is not necessarily 750, greater than 380 can be).
2. Insert one end of the red and black stylus into the com and VΩmA sockets of the multimeter respectively, the black stylus into the com socket and the red stylus into the VΩmA socket.
3. Open the multimeter, the other end of the two stylus and the line to be measured in contact (Note: three-phase electricity between each fire wire and zero line voltage is 220V, the voltage between the two fire wire is 380V)
4. The final reading displayed on the screen is the voltage value to be measured.
