2X 6IN1 Din Rail Monitor Voltage Current Power Factor Active Electric Energy Frequency Meter VOLT AMP AC 250-450V 100A

Application : 1. Connect the measure voltage to the 1 and 2 terminal 2. Connections of meter with internal current transformer as 1. Make the wire through the hole in the meter and the direction chose arbitrarily. 3. Connections of meter with external current transformer as 2. Make the wire through the hole in the meter and connect the two wires of the secondary transformer to the 3 and 4 terminal. 4. When power on the meter display the measure parameters. 5. When power on you can press the button of last for 5 seconds then the electric energy will to be zero and start to cumulate when release the button. And when power off the meter can save the value of electric energy and go on cumulating data when the meter power-on . Attention: The meter can only use for measure 45-65Hz AC electricity.
