press key to switch input or output voltage measurement, OUT indicator shows output voltage, IN indicator shows inputput voltage.
Onboard voltage meter self-calibration :
voltmeter shows output voltage, Press right button for 2 second ,Voltmeter and output voltage indicator "OUT" Synchronous flashing, At this point enter output voltage adjustment mode;
when input voltage voltmeter displays, Press right button for 2 seconds Voltmeter and an input voltage indicator "IN" Synchronous flashing, At this point enter adjustment mode input voltage;
press right button, Voltage rise, press left button, Voltage reduction; Since the voltage is less than the value of a unit of 0.1V, So you need to continuously press 1-5 times to see voltmeter changed 0.1V, Specific continuous button several times depending on the current display voltage, the higher the voltage, the fewer the number of press.
After voltage adjustment is completed, Long press the right button two seconds after the release, You can now exit the voltage calibration mode, All parameter settings are saved automatically power down.
Note:
Some customers report: ". module can not be adjusted, output voltage is always equal to the input voltage" When you encounter this problem, please counter clock wise rotation of the potentiometer 10 laps or more, then you can adjust output voltage Because. the factory default output voltage 20V
