Formula: OFF(TEMP target value) = TEMP(target value) - TEMP(current value) + OFF(TEMP current value).
OFF(HUM target value) = HUM(target value) - HUM(current value) + OFF(HUM current value).
Example (fig.19)：
If TEMP target value is 25.0, current value is 23.0, current value of OFF(TEMP) is -0.2.
Then "OFF(TEMP target value)=25.0-23.0+(-0.2)=+1.8".
If HUM target value is 36.0, current value is 33.0, current value of OFF(HUM) is +1.5.
Then "OFF(HUM target value)=36.0-33.0+(+1.5)=+4.5".
Increase "OFF(TEMP)" to +1.8°C
Increase "OFF(HUM)" to +4.5%rh

Note: 1. Please ensure that you can calibrate under fresh air outdoors.
2. During the calibration process, please do not perform other operations until the
calibration is successful and you return to the previous level screen.
2. TEMP & HUM Calibration: You can calibrate the PM2.5 value by adjusting the "K" factor.
