Extra Info

Calibration method:

Power-off status, press and hold the left button access the power, the display starts flashing, release the left button. using multimeter measured the output terminal voltage, if the measured voltage is greater than 5V, press the left button reduced the voltage to 5V; if the voltage is less than 5V, press the right button to increase the voltage to 5V. When the LCD display voltage of 5V(sometimes it shows 4.99V), turn off the power, the calibration is complete.
