Description D52-2066 guide rail type digital display multifunctional measuring instrument D52-2066 guide rail type digital display multi-function meter simultaneously displays 6 parameters such as AC voltage, AC current, active power, power factor, frequency and electric energy on the instrument. The meter uses a color full-view high-definition LCD display to display the measurement results. Specification Measurement accuracy: 1%2 words Measuring range: AC voltage AC40-300V, AC200-450V Alternating current: AC0-100A, current display resolution is 0.01A Power frequency: 45Hz-65Hz Power factor: 0.00-1.00PF Active power: the measurement range is 0-45000W, the display resolution between 0-9999.9W is 0.1W, and the rest is 1W Electricity: the measurement range is 0-99999kwh, the minimum display resolution of 0-999.99kwh is 0.01kwh 1000.0-9999.9kwh minimum display resolution is 0.1kwh The minimum resolution of 10000.0-99999kwh is 1kwh Measuring speed: about 2 times per second Dimensions: 54*80*64mm Installation method: rail type Package Included 1 D52-2066 multi-function instrument Note The measuring voltage range of this instrument is 200-450V and only applicable to the city power supply of pure AC 45-65Hz, and the measuring range is 40-300V. Please pay attention to purchase To measure 110V 220V voltage, please check AC40-300V, and measure 380V voltage to check 200-450V! If 200-450V is used to measure the voltage of 220V, the meter measurement is inaccurate, please pay attention! To measure the ABC three-phase voltage at the same time, AC40-300V must be used, and the premise equipment must have a neutral line, and three pieces need to be purchased! If you buy AC200-450V, only one of the three phases can be measured.
