Features:
1. This multi-functional meter can simultaneously measure and display the AC voltage, AC current, active power and electricity consumption.
2. Using color high-definition LCD screen to display the data.
3.180 degrees viewing angle without dead ends.
4. With save function / memory function: When power down, the meter will automatically save the current electricity consumption. And it will read this value and continue to accumulate after power on.

Instruction:
1. Wire according to the wiring diagram on the picture. Connect the secondary terminal of the current transformer (Green terminal) to the blue terminal of this meter, and then lead the wire of measuring circuit across the middle hole of the current transformer.
2. Connect the lead wire of voltage measurement to the green terminal of the meter. Then you can measure voltage and read measurement results.
3. Power on, and the meter will display the measured results.
4. Press the button for 5s, then all the measured and accumulated value will be cleared.

Package Included:
1 x Meter
Note:
1. The voltage input (green) terminal and the current transformer secondary input (blue) wiring terminal wiring can not be wrong, otherwise the instrument will be damaged
2. This instrument is only applicable to the AC 50-60HZ mains power, can not be used for square wave, the inverter output and the correction is positive Hyun wave circuit measurement, or instrument will be damaged
3. The installation process can not be squeezed instrument meter LCD screen, otherwise there will be garbled / broken code situat
