Control - Ecom EN2 Operating Instructions Manual

11. 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 center. 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):
- battery voltage (charging status);
is displayed as a symbol in all menus:
Full charge
- operation hours since last service
- total operation hours
- date of the next recommended service
- phone number of the next service center
- software version
- serial number
- amount of CO switch-offs
- error amount
- Collection of the last maintenance
