The digital multifunction meter can simultaneously measure and display 6 parameters such as AC voltage, AC current, active , factor, frequency and electric energy.The display part of the instrument adopts a color high-definition liquid crystal display.SpecificationMeasurement accuracy: 1% 2 wordsAlternating current: AC0-99.99A, current display resolution is 0.01A, when it exceeds 100A, it will display 100.0Afrequency: 45.0Hz-65.0Hzfactor: 0.00-1.00PFActive : the measurement range is 0-45000W, the display resolution between 0-9999.9W is 0.1W, and the rest is 1WElectricity: The measurement range is 0-99999kwh, the minimum display resolution of 0-999.99kwh is 0.01kwh 10000.0-9999.9kwh, the minimum display resolution is 0.1kwh,The minimum resolution of 10000.0-99999kwh is 1kwhMeasuring speed: about 2 times per secondHole size: diameter 22mmSave function/memory function: automatic save function: when the is off, the meter will automatically save the current energy value, and the meter will read the value after the on, and continue to accumulate.AC: AC 250-450VMaterial: plasticcolour: WhitePackage Contents:1 x meterOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
