Onboard voltmeter self-calibration methods:
1, An on-board voltage meter display output voltage, long press the right button for 2 seconds after the release, and the output voltage voltmeter indicator "OUT" synchronous flashing, this time into an output voltage adjustment mode;. Similarly, the voltmeter shows When the input voltage, long press the right button for 2 seconds after the release, voltmeter and input voltage indicator "IN" synchronous flashing, then enter the input voltage adjustment mode;
2, Tap the right button, the voltage increases one unit, touch the left button, a voltage reduction unit; due to the voltage value of a unit is less than 0.1V, so you need to press 1-5 times in a row to see the voltmeter changed 0.1V, continuous button several times depending on the specific voltage value currently displayed, the higher the voltage the current display, the fewer the number of press;
3, After the voltage adjustment is completed, press the right button two seconds after the release, this time to exit voltage calibration mode, all parameters set to automatically power down to save.
Note: You only need to calibrate this adjustment method can get a precise voltage value across the entire voltage range, this feature is designed to meet your requirements and design a higher accuracy, ease of use.

Для дроссельного DC-DC преобразователя выходное напряжение не может быть меньше входного
