DL69-2047 5 In-1 Multi Function Energy Meter Voltmeter Ammeter Power Factor Power Meter(80~300V ~100A ) Item Type: Multi-Function Energy Meter Measurement Accuracy: 1% ± 2-digit Measuring Range: AC Current: AC0.00-100.0A, the display resolution is 0.01A when the measurement current is less than 100A, and the current display resolution is 0.1A when the measurement current is greater than 100A, the range is automatically converted. Electric Energy: 0.000-99999Kwh, automatic conversion of decimal point Power Factor: 1.000-0.000 Measuring Speed: About 2 times per second Use and Wiring Method: 1. According to the wiring diagram of the drawing, connect the secondary end (green lead) of the current transformer of the instrument to the blue terminal of the meter, and pass the wire of the measuring circuit once through the middle hole of the current transformer. 4. When it is necessary to measure the electric quantity (electric energy) from zero, press the button (SAM CK) to convert the measurement function to the electric quantity (electric energy) measurement function, which is the right function of the 5-digit green LED digital tube display on the meter display. The indicator light indicates the position of Kwh, then press and hold the (SAMCK) button for 5 seconds. The 5-digit green LED digital tube displayed by the electric energy (electricity) all displays zero, and the release button (SAM CK) power (electricity) ) shows the measurement from zero.
