Use Steps:
Connect load at OUT+ and OUT- at first.Please note the positive and negative.
Connect power supply at IN+ and IN-.Please note the positive and negative.
Press the button to switch the display input or output voltage value.

Warm tip:
When the high power load is connected, because the shock current of the start-up is very limited, it is recommended to start up and then connect the load.
