CO value:
Display of the value currently being measured by the CO sensor
The CO value specifies the currently-measured CO concentration. The specified number is
calculated as the difference between the current measurement value and the stand-by value
stored in the detector. The CO concentration displayed lies in the range between 0 (normal
operating condition) and 555 (max. measurement value of the sensor).
EMC value:
Indicates EMC level. There is a current EMC value (short-term measurement) used during/right
after installation of the detector and average EMC value (long-term measurement) used during
operation of the detector.
