Just need to calibration once for the first time! Voltage calibration: In the case of power down, press and hold the "SET" button, power on, enter the voltage calibration mode, the LCD screen starts to flash, release the set button, press the "Set" key to add, "OK" to reduce, calibrate correct input voltage, such as: the input voltage is 12.65V, then adjust the current voltage to 12.65V, after 2 seconds it automatic save, power off and exit to complete the calibration! Current calibration: For no-load current display, or current is too large! In the case of power off, press and hold the "OK" button, power on, enter the current calibration mode, the LCD screen starts to flash, release the "OK" button, press the "Set" button to add, "OK" button to reduce, calibrate correct current, such as: no load display 0.02A, then adjust to 0.00A, after 2 seconds it automatic save, power off and exit to complete the calibration! Special Note: Some customers feedback that the output voltage can not be adjusted, this is due to the factory default voltage is 20V. When you encounter this problem, please counterclockwise rotation ADJ-V potentiometer 10 laps above, until the voltage value changes, and then the module can be normal adjustment of the voltage. Note: USB output voltage and the module output voltage needs to be consistent, when the USB indicator does not light, means USB has no output, when the USB light is set, it is not fixed 5V output, when charging USB device please make sure the voltage is 5V, if higher than 5.5V screen will flash, it will be reminded to adjust the voltage, otherwise it may damage your device, USB output power is turned off by default, to ensure that mistakenly plug USB will not damage the device. Setting Description: Setting key can be set to four kinds of display mode: 1. F-0 mode: display output voltage; 2. F-1 mode: display input voltage; 3. F-2 mode: alternately display input and output voltage; 4. USB mode: display USB output voltage and turn on or off the USB output; Instructions: press the "set" button, the cycle shows four kinds of display mode, the corresponding indicator light will on/off, press the "OK" key to save and exit, press the "OK" button to switch the LCD backlight.
