days.

The sensor attached to your instrument will require periodic
servicing and maintenance. The instrument can automatically
remind the user when the next sensor service is due.
Select enable and enter a delay in days. This should be
•
validated by a level 3 user.
The display shows the current instrument date and time, the
next sensor service due date and time, and the remaining
days.
The next service date is updated when the button "Service
done" is pressed after a service. The event "Service required"
is generated when the delay has elapsed.
Select either General or Zero diagnostic from the menu.
General will display values for the measurements in the
sample, while zero is used to display values when the gas
concentration is at zero (e.g. during a zero calibration using
pure nitrogen as the calibration medium).
The screen layouts are identical for both diagnostic options,
and show useful information for troubleshooting purposes.
The first screen displays measurement information, with a
status (OK or NOK) alongside. A status of NOK indicates the
value is outside of the acceptable minimum or maximum
value. To view the acceptable range limits press the Show
criteria button.
The criteria screen displays the acceptable range limits
(minimum and maximum values) for more in-depth
troubleshooting.
