The self-calibration method of voltmeter: 

  1. When the voltmeter shows output voltage, long press the right button for 2 seconds, then release, voltmeter and "OUT" LED flash in synchronization. Now the voltmeter enters into output voltage calibration mode. Similarly, when the voltmeter shows input voltage, long press the right button for 2 seconds, then release, voltmeter and "IN" LED flash in synchronization, now the voltmeter enters into input voltage calibration mode.
  2. Touch the right button, the voltage rises a unit; Touch the left button, the voltage drops a unit. Due to a unit is less than 0.1 V, so you need to continuously press 5 times to see that the voltmeter changes 0.1 V
  3. After calibration, long press the right button for 2 seconds, then release. Now the voltmeter exits the voltage calibration mode. All the parameters will be saved automatically.(Note: Once calibrate the voltmeter, you can get the accurate voltage value on the whole voltage range) 

 

Note1 : Please enchance cooling when the output power or output current is large
Note2 : Factory default of output voltage is ~20v. Please rotate the potentiometer anticlockwise for more than 10 circles when the output voltage can not be adjusted, or always equals to input voltage
