Setting CO-Limit (without purging)
If the CO limit value is exceeded, the colour of the measured CO values
changes (red).
CO-purging
NOTE
Please note that the setting of the CO limit value with
purging depends on the configuration of your analyzer.
If the CO value exceeds the CO threshold, then the measured value is
displayed red and air purging pump is activated. This will protect the CO
electrochemical cell from too high CO gas concentrations.
If the CO value decrease below the CO threshold, then the CO value will
be displayed again in black colour.
Air purging pump is still running and can be deactivated only by access-
ing the “menu” key and confirm “purge pump off”
T
he actual CO value will then be displayed again.
If a measurement with active purging will be stored, the device docu-
mented the device the CO value as CO limit value.
NOTE
Unit switching: 10000pmm values are displayed in%.
