multi-funciton digital meter can measure and display AC voltage, AC current, active power and electric energy at the same time. The display part of meter use high-definition color LCD screen.

Technical Indicators

1. Accuracy: 1% 2words
   
2. Range:
     - AC voltage: AC 200-450V
     - AC current: AC 0-99.99A, minimum resolution is 0.01A.
     - Active power: 0-45000W. 0-9999.9W minimum display resolution is 0.1W, otherwise Minimum resolution is 1W.
     - Electric energy: 0-9999999Kwh
     - 0-9999.999kwh minimum resolution is 0.001kwh
     - 10000.00-99999.99kwh minimum resolution is 0.01kwh
     - 100000.0-999999.9kwh minimum resolution is 0.1kwh

5. Installation Size:76*39
   
6. Auto-saving: when power off, the electric energy will be saved. The saved electric energy will be accumulated continue when the meter power-on next time.
   Connection graph

Application Method

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 last for 5 second, the electriv energy will to be zero.
   

Attention

1. The meter will be destroyed when you make wrong connection method with voltage input(green terminal) and secondary current transformer(blue terminal).
   
2. It will be destroyed when use to measure square wave, output of inverter and correction sine wave.
