Cedex Bio System 2 Introduction to the instrument
Maintenance
Results
You can check the results on the screen as soon as they are calculated.
Units Results are normally given in your lab units. The units can be configured.
Flags Result flags are test-specific. They indicate that the limit of an internal check was
exceeded or not reached.
System flags point to the status of the result within the process of analysis; for
example, they tell you that the result has not been accepted or that is has not been
transmitted to the host successfully.
Printing results You can print all or selected results on the built-in printer.
Validating results All results need to be validated (result accepted, test rerun or repeated).
Result flags help you identify critical results and point to possible actions that need to
be taken.
Each test must have accepted calibration results; tests whose associated calibration
results are not accepted cannot be performed.
Ratio results The user can manually define ratios. Ratio results are handled like any other sample
result, with the exception that they cannot be accepted by the user. They are
automatically accepted if all their constituent results are accepted.
Repeating and rerunning tests If a result is flagged, you may decide to run a test again. You can either perform
exactly the same test (Repeat) or perform it with a different predefined dilution
(Rerun).
Storing results The Cedex Bio instrument is designed to hold the sample results of one day’s
analyzing. Therefore, you need to back up the data regularly to an external medium.
(Backing up results is an integral part of the End Shift wizard.)
The QC results of the previous and the current months are stored on the system.
Up to five calibration results are stored on the system for each test.
Maintenance
Completing maintenance actions correctly and on time helps to ensure smooth and
uninterrupted operation of your instrument.
Maintenance scheduling The Cedex Bio instrument facilitates performing the maintenance actions in bundles
at the times that suit your laboratory work processes. To that purpose, you can define
in the configuration settings one day of the week as your maintenance day.

For information on scheduling maintenance actions, see Scheduling maintenance actions
on page B-158.
All maintenance actions can be performed any time.
