Output voltage (input voltage) calibration steps for LM2596S Input 4V-40V Output 1.25V -37V Upto 3A Adjustible With Digital Display

Step 1 : adjust the right button so that ""OUT"" (""IN"")LED lit up, the voltmeter shows the value of output voltage; press the right button more than 2 seconds, release, voltmeter and ""OUT"" (""IN"")LED flashes in synchronization so that you enter the output voltage calibration mode.

Step 2 : Press the right button (normal speed), the voltage value is adding one unit; On the left button, minus one unit; because of a unit is less than 0.1V, the minimum voltage display 0.1V, so you need to continuously press 1-5 times to see the voltmeter change 0.1V, how many times voltmeter change 0.1V through the key, depending on the current display voltage, the higher the tension, the less the number of presses.

Step 3 : press the right button more than 2 seconds, release, to enter the output voltage calibration mode. All parameters automatically turn off.
