AC Current Meter, IJJ 80-300V 100A Digital Multimeter Voltmeter Ammeter, LCD Display Voltage Amperage Detector Volt Amp Tester Monitor Gauge Panel with Current Transformer CT D85-2042AG

Main Specifications 1. Measurement accuracy: 1% ± 2 words 2. Display: Voltage display: yellow LCD, current display: blue LCD 3.Measuring range: AC voltage: AC80.0-300V, AC200-450V Alternating current: AC0?100.0A, AC0?199.9A Customers can select the appropriate voltage and current ranges according to their needs) 5. Measuring speed: about 2 times per second 6. Dimensions: 70×39×40mm 7. Installed size: 68×38mm Precautions 1. The voltage input (green terminal) and the secondary input of the current transformer (blue terminal) cannot be connected wrongly, otherwise the meter will be burnt out. 2. This meter is only suitable for pure AC 50Hz mains power supply. It cannot be used for square wave, inverter output and modified sine wave circuit measurement, otherwise the meter will be permanently damaged 1. The diameter of the transformer hole is 15.5mm, which can meet the national standard 21-25 square (mm) standard copper wire to pass through. 2. The diameter of the 200A transformer hole is 24mm, which can meet the national standard 30-45 square (mm) standard copper wire passing through Household check: 80-300V~100A Note: If you want to measure ABC/three-phase voltage and current at the same time, you must purchase 3 meters, three-phase 4-wire check 80-300V/three-phase 3-wire check 200-450V Use and wiring method 1: Connect according to the wiring diagram of the attached figure, connect the secondary end of the current transformer with the meter (green lead) to the blue terminal of the meter, and pass the wire of the measurement loop through the middle round hole of the current transformer . 2. Connect the voltage measurement lead to the green terminal of the meter. Then turn on the measurement voltage. Start reading measurement results
