1. Press the first "K1" digital tube hundred digits to flash, adjust the lower limit hundreds digit, press "K2" 0-9 to change and adjust
2. After adjusting the hundred digit, press the second "K1" digital tube ten digits to flash, the lower limit tens digit is adjusted, press "K2" 0-9 to change and adjust
3. After adjusting the tens digit, press the third "K1" digital tube to blink, and adjust the lower limit ones digit, press "K2" 0-9 to change and adjust
4. After adjusting the units digit, press the 4th "K1" digital tube to blink the hundred digit, and adjust the upper limit hundreds digit, press "K2" 0-9 to change and adjust
5. After adjusting the hundred digit, press the 5h "K1" digital tube tens digit to flash, adjust the upper limit tens digit, press "K2" 0-9 to change and adjust
6. After adjusting the tens digit, press the 6th "K1" digital tube to blink, and adjust the upper limit ones digit, press "K2" 0-9 to change and adjust
During the above adjustment process, if no key is pressed for adjustment within 2 seconds, it will automatically jumping back to the initial interface, and the setting data will be saved
