4.Potentiometer introduction:
    1.Long press means need keep press for more than 10second.
    2.Default display duty cycle.
    3.Normal display mode:
        3.1>.Short press potentiometer:Turn ON/OFF output signal.
        3.2>.Long press potentiometer:Enter parameter set mode.
        3.3>.Rotate potentiometer clockwise:Increase duty cycle value.
        3.4>.Rotate potentiometer counterclockwise:Decrease duty cycle value.

    4.Parameter set mode:
        4.1>.Short press potentiometer:Select parameter.Switch select Power-ON ON/OFF State,Lower Limit Value of duty cycle,Upper Limit Value and Output Frequency.Power-ON ON/OFF State is default output state when power ON. Lower Limit Value display in ‘L’ and 2bit number.Upper Limit Value display in ‘H’ and 2bit number or ‘100’.Output Frequency display in ‘F’ and 2bit number.
