Instructions : 1. According to the wiring , connect the plug two-wire of the current transformer to transformer the input on meter, make the current return conductor 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 . 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. 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 : AC50.0-300.0V 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 is 0-30000W;and when voltage AC250-450V, the measuring range of is 0-45000W. The resolution of is 0.1W when the measure range between 0 and 9999.9W, and when 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 per second 4. Hole: diameter 22mm 5. Autosave: When the meter power is off, the current eletric energy value will be automatically saved . the meter will read the value after the power on and going to keep adding to the saved value. number.
