How to set-up:

1. Power up the module with a stable and accurate power supply , such as a 24V power supply, then shot press the button on the right side to select which one do you need to adjust (input or output), and long pressing (press time > 2S) the button(right) makes the module enter the calibration model, after releasing the button, the related LED would blink to indicate which voltage is now calibrating, and the numeric display blinks the correction value.
2. Short press the button to change the correction value, Short press the button on the right side, voltage increases one unit, Short press the button on the left side, voltage reduce one unit, for example, if your power supply is 24V, but the result of voltage meter is 13.8, you need to set the value to 24V.
3. Long press button on the right side(press time ≈ 2S), to store the voltage correction value.
4. Calibrate the output voltage in the same way above; The correction value will be stored in nonvolatile memory.
