Power on module while not connect to load, then adjust "V-ADJ" potentiometer clockwise to increase, counterclockwise to decrease. Due to large output capacitance capacity, response will be slow when adjust high voltage to low voltage.
Adjust "CC A-ADJ" potentiometer counterclockwise about 30 circles to minimize the output current before connecting to load. Then adjust "CC A-ADJ" clockwise to the current value you need.If you use the module for battery charging, connect to output after battery is fully discharged. Because if the more energy is left in battery, the less charging current will be.
Low Input Voltage Protection Adjustment:
If we set a low input voltage protection for a 12V battery, connect input to a 10V voltage, then adjust RV1(clockwise to increase, counterclockwise to decrease) till UVLO light up. Now the protection voltage is 10V, that is to say, when battery voltage drops to 10V, module won't step up voltage and the output voltage will be same as input voltage.
