Features: brand new and high quality D85-2058 digital display multifunction meter is to display the measured AC voltage, AC current active power, power factor, frequency, electric quantity and electric energy on the same screen on one meter. The display part of the instrument adopts a color high-definition LCD display. The display accuracy is 0.1kwh, when between 10000.0 and 999999kwh, the display accuray is 1kwh The D85_2058 ac power meter voltage measuring range is AC40-300V/AC200-450V(optional), current measuring range is 0-100A, active power range is 0-30000W(AC40-300V) /0-45000(AC200-450V), electric energy range is 0-9999999kWh.Color LED Display: the watt meter panel adopts clear LCD displaying accurate voltage, ampere, active power and electric quantity measuring values. With fast measuring speed of 2 times per second. Auto-saving: when power off, the electric energy will be saved. the saved electric energy will be accumulated continue when the meter power-on next for time Specifications: Model: D85-2058 Range: AC Voltage: AC 40.0-300.0V / 200.0-450.0V (you should select he suitable type of meter when your making order) AC Current: AC 0-99.99A , minimum resolution is 0.01A Power Frequency: 45.0Hz-65.0Hz Power Factor: 0.00-1.00PF Speed: 2 Times Per Second Size:approx 70x39x40mm / 2.76x1.54x1.57 inches Package Includes: 1 x Digital Power Monitor note: Due to the problems of lighting effects and shooting angles, there will be certain tolerances in the product, please understand. Please allow 0-1cm error due to the manual measurment. The wires of voltage input terminal (green) and CT- secondary input terminal (blue) cannot be connected wrongly, or the meter will be damaged. The screen cannot be squeezed during installation, or there will be garbled code or break code. The 200-450V specification of this meter cannot be used for square wave inverter output and the corrected sine wave circuit for measurement, otherwise the meter will be damaged. If you purchase multiple instruments for use, the for transformers cannot be used interchangeably.
