Product 1. LCD color display true color screen 178 degrees wide viewing angle2. Measure AC voltage, current, power, electricity, frequency, power factor (6 major functions)3. The power (Kwh) has a memory function, and the accumulated power consumption will be cleared after long pressing the round hole on the side of the meter for 5 seconds.4. It is widely used in the measurement application industry, chemical industry, power plant, automation equipment, DOS system, electromechanical equipment and other places.5. Simple to use, provide wiring diagram6. Display color: red, orange, yellow, white, green and blueThe digital multifunction meter can simultaneously measure and display 6 parameters such as AC voltage, AC current, active power, power factor, frequency and electric energy. The display part of the instrument adopts a color high-definition liquid crystal display.Main Specifications1. Measurement accuracy: 1% 22. Measuring range: AC voltage: AC50.0-300.0V, (or AC250.0-450.0V can be customized if necessary),Alternating current: AC0-99.99A, current display resolution is 0.01A, when it exceeds 100A, it will display 100.0APower frequency: 45.0Hz-65.0HzPower factor: 0.00-1.00PFActive power: 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 1kwh3.Measuring speed: about 2 times per second4. Dimensions: 494752(mm)5. Hole size: diameter 22mm6. Save function/memory function: automatic save function: when the power is off, the meter will automatically save the current energy value, and the meter will read the value after the next power on, and continue to accumulate.Use and wiring method1. Connect the wires according to the wiring diagram in the attached drawing, and insert the two-wire plug of the secondary end of the current transformer of the instrument into the secondary input end of the instrument. Pass the main loop wire of the current test through the middle round hole of the current transformer.2. Connect the voltage measuring lead to the measuring voltage input terminal of the meter. Then turn on the measurement voltage. Start reading the measurement results.3. The power reset button of the meter is on the lower right side of the meter. When power is required to be reset, use a circle with a diameter of less than 2mm and gently press it in the reset hole for 5 seconds to reset the accumulated power value to zero.PrecautionsThe 250-450V range meter is only suitable for pure AC 50 mains power. It cannot be used for square wave, inverter output and modified sine wave circuit measurement, otherwise the meter will be damaged. The 50-300V range meter is not affected.Product List:1*Multi-function voltage current and power display frequency meter
