8.1.1.2 Analyzer status: Status: Maintenance request
This dialog indicates the logged maintenance requests. A
maintenance request is set if the values of certain parameters
have reached defined limits, but the analyzer is still able to
measure (e.g. AUTOCAL deviation or O
2
sensor status; see
also section Analyzer status: Status: O2 sensor status
(Page 106)). A corresponding message is output in alphanu-
meric text.
Access is protected by code level 1.
Following access to the maintenance request list you can:
• Display all recorded faults in succession using the < → > key
•
Delete the currently displayed fault message using the
<ENTER> key. If present, the next maintenance request is
then displayed. You should delete all maintenance requests
whose causes have been eliminated.
Note
If the analyzer is in measuring mode, you can recognize the
occurrence of a maintenance request in that an "M" appears at
the right edge.
8.1.1.3 Analyzer status: Status: AUTOCAL deviation
This dialog indicates the deviation in setpoint between several
AUTOCAL procedures. The parameters have the following
meanings:
•
The text in the two top lines provides information on the
number of AUTOCAL procedures which have been carried
out since the reference value for AUTOCAL was last set
(see section Configuration: Special functions: AUTOCAL
deviation (Page 144)).
• Deviation is the measured deviation of the actual value from
the reference value, displayed in % of the set measuring
range (with autoranging, range 1 is assumed). This
deviation must not be above the set maximum value.
•
Max. allowed is the maximum permissible value for the
deviation. Refer to section Configuration: Special functions:
AUTOCAL deviation (Page 144) for setting the maximum
value.
This function is specific to the component.
