Control - Ecom EN3 Operating Instructions Manual

8. Control

The electrochemical sensors for gas analysis are submitted to a wearing process and do
age. They alter their output values along the time depending on the gas concentration, the
exposure time and the soiling grade of the sampled gas.
The program monitors the sensors and corrects drifts. But if the drifts and the correlated
measurement errors increase, an error message is displayed. In this case the corresponding
sensor must be changed by an authorized service centre.
The control menu informs about the current status values for the sensors. Further
information is also consigned on 3 display pages (use cursor keys to scroll)
The following status values are available:
- battery voltage (charging status); is displayed as a symbol in all menus:
