"CAL" icon and calibrating value (75,2% if at 25ºC) are blinking on the LCD with current temperature at the left.
Meter is now calibrating. Wait about 60 minutes until blinking stops, then calibration is completed and it returns
to normal mode.
NOTE: Users can also calibrate either point. To calibrate 33% only, pres CAL/ESC key to exit when 33%
calibration is completed. To calibrate 75% only, press UP or DOWN key within 5 minutes while initializing 33%
calibration. It will skip 33% calibration and enter 75% calibration mode.

Solution
Check if the adaptor is well plugged
Check if the air flow channels on the rear are blocked
Meaning
CO sensor damaged

The value is under range
The value is over range
The original data error results in this error (RH, DP, WB)
Too low voltage to measure CO
Check if the adaptor output is 12V
