Before initial use, first ensure the module is unpowered and unloaded. Using a flathead screwdriver on the copper head of the blue potentiometer (align it toward your chest), rotate the potentiometer counterclockwise to the end (at least 30 full turns) until you hear a "click". Finally, power on the module, monitor the output voltage with a multimeter, and rotate the potentiometer clockwise to achieve the desired voltage.
