XL6009 4A DC Boost LED Display Voltmeter
In the moderate press, access the adjustment mode. Adjust the displacement (which is set at 0 by default) to correct any voltage misuse. Follow regulations for a short duration, or restore for a longer period.
When the long press function is activated, the module enters a low power consumption state and turns off the digital tube and lights. To revert back to normal operation, simply click the button once more, and the display screen will return to its usual state.
