Self-calibration method of onboard voltmeter:
1. When the on-board voltmeter displays the output voltage, press and hold the right button for 2 seconds and then release, the voltmeter and the output voltage indicator "OUT" flash simultaneously, and then enter the output voltage adjustment mode; similarly, the voltmeter displays When inputting voltage, press and hold the right button for 2 seconds and then release, the voltmeter and the input voltage indicator "IN" flash simultaneously, then enter the input voltage adjustment mode;
2. Touch the right button to increase the voltage by one unit, and touch the left button to decrease the unit by one voltage; because the voltage value of a unit is less than 0.1V, you need to press 1-5 times to see the voltmeter Changed by 0.1V, the specific number of consecutive key presses depends on the currently displayed voltage value. The higher the current displayed voltage, the fewer the number of presses;
3. After the voltage adjustment is completed, press and hold the right button for 2 seconds and then release. At this time, you can exit the voltage calibration mode, and all parameter settings are automatically saved after power-off.
Note: In this adjustment method, you only need to calibrate once to get the accurate voltage value over the entire voltage range. This function is designed to meet your higher accuracy requirements, please rest assured
