Use Guide:

This multi-function Digital meter can measure AC voltage, AC current, power factor, active power, electric energy and power frequency. The meter display part adopts the color high-definition LCD screen.

Technical Indicators:

1.Accuracy: 1%+2 words

2. Range:

• AC voltage : AC 50. 0-300.0V  or AC 250.0-450.0V

• AC current: AC 0.0-99.99A (the accuracy is 0.01A when measure signal lower than 100A, when measure
  signal higher than 100A, the meter will show 100.0A)

• Power frequency: 45.00-65.00Hz

• Power Lactor: 0.00- 1.00PF

• Active power: when voltage AC40-300V, the measuring range of real power is 0-30000W；and when voltage AC250-450V, the measuring range of real power is 0-45000W. The resolution of real power is 0.1W when the measure range between 0 and 9999.9W, and when real power more than 9999.9W, the resolution is 1W.

• Electric energy: 0-99999kwh (The display accuracy is 0.01kwh when the electric energy between
  0-999.99kwh, 0. 1kwh when the electric energy between 1000.0-9999.9kwh, 0.01kwh
  when the electric energy between 100000-99999kwh

3. Speed: 2 times per second

4. Size: 49*47*53mm

5. Hole: diameter Φ22mm

6. Auto save: When the meter power is off, the current eletric energy value will be automatically saved. the meter
will read the value after the next power on and going to keep adding to the saved value number.

 

Application Method:

1. According to the wiring diagram, connect the plug two-wire of the current transformer to transformer the input on ​meter, make the current return conductor across the hold which in the middle of the current transformer.

2. Connect the voltage measurement to the voltage input terminal of the meter. Then turn on and measure the voltage ​to start to read the measure result.

3. The electric enengy reset button is on the right-bottom of the meter, you can press the button with a needle last for ​5 seconds, then the electric energy will be reset.
