Determine the operating current and\r\nmaximum operating voltage that you need to drive the LED; 2. Adjust the\r\nconstant voltage potentiometer, adjust the output voltage to 5V or so. 3. With\r\nthe multimeter 10A current block output short-circuit current measurement, and\r\nadjust the constant current potentiometer to output current to reach the\r\npredetermined LED operating current; 4. Adjust the constant voltage\r\npotentiometer to make the output voltage reach the highest working voltage of\r\nLED; 5. Connect the LED, test machine. (1,2,3,4 steps for the module input\r\npower, the output no load LED lights.)★Communication Protocol Description: 1.\r\nThis module has the function of communication with the computer. Can\r\nfacilitate the computer to read the module current and voltage data, 2.
