DC-DC Down Convertor 5A

Onboard voltmeter auto-calibration method: 1. Onboard voltmeter shows that the output voltage, long press the right button 2 seconds to loosen, voltmeter, and the output voltage indicator light "OUT" synchronous flash, at this time into the output voltage regulation mode;Similarly, when the input voltage IN the voltmeter display, long press the right button 2 seconds to loosen, voltmeter, and the input voltage indicator light "IN" synchronous flash, at this time into the input voltage adjustment mode; 2. Touch the right key, the voltage of a unit, a light touch on the left key, voltage reduce a unit;Due to a unit of voltage is less than 0.1 V, so you need to press the 1-5 consecutive can see the voltmeter change 0.1 V, the concrete continuous button several times depends on the current display voltage, current shows that the higher the voltage, the fewer the number of pedestrian. 3. After the voltage adjustment, long press the right button for 2 seconds after the release, at this time to exit the voltage calibration mode, all the parameters set up automatic electricity saving.
