Voltmeter calibration
Step 1. Press the right button so that the "OUT" LED is lit, the voltmeter shows the output voltage value; press and hold the right button for more than 2 seconds, release the button, the voltmeter and the "OUT" LED will flash synchronously so that you enter the output voltage calibration mode.
Step 2. Press the right button to add. Press the left button to subtract. As the step is less than 0.1V, the minimum voltage reading will be 0.1V, so you will need to press 1-5 times continuously to make the voltmeter change to 0.1V.
Step 3. TPress and release the right button for more than 2 seconds to exit the output voltage calibration mode. All set parameters are automatically turned off and saved.
Input voltage calibration steps
Step 1. Press the right button so that the "IN" LED lights up, the voltmeter displays the input voltage value; press the right button for more than 2 seconds and release it, the voltmeter and the "IN" LED flash synchronously so that you enter the input voltage calibration mode.
Step 2. and 3. correspond to the output voltage calibration method.
