1. According to connection graph, connect the green wire of secondary current transformer to the blue terminal of meter and make the wire of measurement circuit through the hole in the current transformer.
2. Supply power and start to measure and display the result.
3. Press down the button on the panel last for 5 second, the electric energy will to be zero.
1.The meter will be destroyed when you make wrong connection method with voltage input(green terminal) and secondary current transformer(blue terminal).
2.The meter can only use to measure 50Hz AC city electricity, it will be destroyed when use to measure square wave, output of inverter and correction sine wave.
1x AC multi-function Voltage Meter
1x CT Current Transformer
