    Hello Muhammad Asif,
    Thank you for writing in.
    There is slight mistake with the picture before but we have amend it, please check it.
    The turn light is an indicator that indicate if the device is charging or full-charged.
    When the device is charging, the turn light is red; when the device is full-charged, the turn light is green.
    The potentiometer for the turn light is used to adjust the turning point current value between charging and full-charged.
    Here is the adjust instruction:
    After setting the output voltage, anti-clockwise turn the CC potentiometer about 20 rounds, then use 20A current of multimeter to short circuit output. Adjust the CC potentiometer to get the current you need to turn the light and then adjust the LED potentiometer until the turn light shows green.

    Hope this can help you.
    Best regards

    Hello Muhammad Asif,
    There is something wrong with the caption of the turn light adjustment.
    But we have amended it and the picture above is right.
    Sorry for our mistake and beg your understanding.
    Have a nice day!
    Best regards
