Press the right key to let the display show the input or output voltage. when the right “OUT” led light, it shows output, the left “IN” led show input.

Note: Some customers report: “The module can not be adjusted, the output voltage is always equal to the input voltage.” When you encounter this problem, please counterclockwise rotation of the potentiometer 10 laps or more, then you can adjust the output voltage. Because the factory default output voltage is 20V.
