9. Control
The electrochemical sensors used for gas analysis are submitted to
a wearing process and age. Along the operation period, they alter
their output values depending on the gas concentration, flow duration
and soiling degree of the measured gases. The programme controls
the sensors and corrects drifts. If drifts and the correlated measure-
ments errors increase, an error message is displayed. In this case
the corresponding sensors must be changed by one of our author-
ised service centres. The actual status of the sensors is displayed in
the control menu. Additionally on two more pages will be displayed
(change the display pages by using the cursers):
-the battery voltage (charging status)
displayed in all menus as symbol:
Battery full Battery ½ full Battery empty
-the phone number of next service centre
-the serial number
-the software version
-the operation hours
-the date of last service
-the number of CO switch offs
-the number of error occurred
-Collection of the last maintenance
