Durable Single-Phase Smart Energy Meter Rail-Mounted Voltage Current Power Frequency Factor Meter

Application Method

• 1.Connect the AC voltage to be measured to the 1st and 2nd terminals of the meter. Ensure the wiring is firm and secure to avoid poor contact that may affect measurement accuracy.
• 2.For the meter equipped with an internal current transformer, follow the connection method shown in Graph 1. Simply pass the circuit wire through the dedicated hole on the meter-there is no restriction on the direction of the wire, which can be chosen arbitrarily based on actual installation needs.
• 3.When using an external current transformer, refer to Graph 2 for wiring. First, pass the measured wire through the hole in the meter, then take the two wires from the secondary side of the external current transformer and connect them to the 3rd and 4th terminals of the meter respectively, ensuring reliable connection.
• 4.After completing all wiring correctly, turn on the power. The meter will automatically start working and display the measured parameters (including AC voltage, current, power, etc.) clearly on the LCD screen.
• .In the power-on state, press and hold the “SAM CK” button for 5 seconds to reset the electric energy value to zero.
• Release the button, and the meter will start accumulating electric energy again. When the meter is powered off, it can automatically save the current electric energy data; upon next power-on, it will continue accumulating based on the saved value without data loss.
