CAUTION
Damage to the CO sensor
If the opening for the supply of fresh air to the CO sensor is closed,
the sensor can not be purged with fresh air and will be damaged or
destroyed during overload.
Fresh air opening
If the CO sensor has been purged sufficiently with fresh air (X disappears
behind CO) and the measured values are within the permissible range, the
fresh air flushing pump is switched off.
The CO indicator in the status bar of the measurement screen no longer
flashes and the status LED <Info> changes from "red" to "green".
The "CO automatic" option can be used to set how the fresh air flushing
pump is switched off after sufficient purging of the CO sensor:
•
automatically
•
must be triggered manually
To deactivate the CO automatic option, deactivate the corresponding option
in the menu Adjustments \ Internal \ CO-Automatic with "No".
To switch off the fresh air flushing pump with the CO automatic deactivated,
press the <F3> key.
