Technical Indicators1. Accuracy: 1%2 words2. Range: AC voltage:AC 50.0-300.0VAC current: AC 0.0-99.99A (the accuracy 1suuruunenmeasure signal lower than 1 00A, when measure singnal higher than 100A,the meter will show 100.0A)Power frequency: 45.00-65.00HzPower actor: 0.00- 1.00PFActive power: 0-30000W (The display accuracy is 0.1W when the active power between 0 and 9999.9w,otherwise the accuracy 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 iecn ne elecrec cnergy between 10000.0-9999.9kwh,0.01kwh.when the electric energy between 100000-99999 kwh.)3.Speed: 2 times per second4.Size: 49x47x52mm5.Hole: diameter 22mm6.Autosave: When the meter power is off, the current electric 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 Method1.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 energy reset button is on the right-bottom of tie meter, you can press the buiton with a needle last for 4. second, then the electric energy will be reset.Package Content1 x AC voltmeter ammeter power meter1 x CT1 x English Manual
