AC Voltmeter Ammeter Wattmeter Power Energy Frequency Meter AC 110V 220V Volt Amp Herz Power Factor Voltage Current MontiorUser GuideD48-2058 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 HD LCD screenTechnical Indicators1 Accuracy: 1%+2 words2 Range:AC voltage : AC 50.0-300.0VAC 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: 45.00-65.00HzPower 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 between 10000.0-9999 9kwh,0.01kwh, when the electric energy between 00000-99999kwh3.Speed: 2 times per second4.Size: 49x47x525.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 eiecuiv enengy reset button is on tne right-bottom of the meter, you can press the buiton with a needle last for4. second, then the electric energy will be reset.Package Content:1 x AC voltmeter ammeter power meter1 x CT1 x English Manual
