When the right “OUT” LED shows output, the left “IN” LED displays input.

Hold the right button for over 2 seconds, then release. The voltmeter and “OUT” LED will flash synchronously, entering output voltage calibration mode.\u003c\/p\u003e\u003cp\u003eStep 2: Press the right button (at normal speed) to increment the voltage value by one unit; press the left button to decrement by one unit. Since one unit is less than 0.1V, the minimum voltage display is 0.1V. Therefore, press the button 1-5 times consecutively to observe a 0.1V change in the voltmeter. The number of button presses required for a 0.1V change depends on the current displayed voltage—higher voltages require fewer presses.\u003c\/p\u003e\u003cp\u003eStep 3: Press and hold the right button for over 2 seconds, then release to exit output voltage calibration mode. All set parameters will automatically save upon release.\u003c\/p\u003e\u003cp\u003e(2) Input Voltage Calibration Steps\u003c\/p\u003e\u003cp\u003eStep 1: Adjust the right button until the “IN” LED illuminates and the voltmeter displays the input voltage value. Press and hold the right button for over 2 seconds, then release. The voltmeter and “IN” LED will flash synchronously, indicating entry into input voltage calibration mode.\u003c\/p\u003e\u003cp\u003eSteps 2 and 3 follow the same procedure as the output voltage calibration method.\u003c\/p\u003e\u003cp\u003eSome customers report: “The module cannot be adjusted; the output voltage always equals the input voltage.” If encountering this issue, rotate the potentiometer counterclockwise more than 10 turns to adjust the output voltage. The factory default output voltage is 20V.\u003c\/p\u003e\u003cp\u003eShipping List:\u003c\/p\u003e\u003cp\u003e1 x LM2596 Buck Power Supply Module\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003ch4\u003eQ: What is the LM2596 DC Step Down Converter Voltage Regulator 4 0 40 1?\u003c\/h4\u003e\u003cp\u003eA: The LM2596 DC Step Down Converter Voltage Regulator 4 0 40 1 is a quality decor pick.
