4.3.5. Modifying Data Entry, Changing Samples
Information about the operation and process parameters for samples that have not yet been analyzed can be
modifi ed during the run. To modify information of measurements that are in active or schedule mode but have
not yet been started, do the following:
1
Double-click on the Status fi eld of the measurement to be modifi ed. The status fi eld will indicate that the
sample is in edit mode.
2
Make desired changes to the measurement.
3
Double-click on the Status fi eld to re-activate the measurement (status: active or scheduled).
■
Wait until the Multi Sample Tray has stopped moving before changing the samples!
4.3.6. Non-Linear Measurements in a Sample Series
Measurements of activated samples are always done in a linear fashion following a sequence of 1–20. If samples
need to be analyzed individually and not in the usual linear ascending order of 1–20, the samples to be analyzed
later should be inactivated and remain in the Edit status for the meantime. When all active samples in the
sample tray are completed, subsequent measurements with the newly activated samples can begin.
4.4 Interrupting a Multi Run
The Start button will switch to a Stop button after a Multi Run has started. Click on the Stop button to pause or
stop the Multi Run. If a measurement is being carried out when the Stop button is pressed, that measurement
will be completed. All scheduled measurements (status: scheduled) will switch to active mode, and the Stop
button will revert to Start. Click on the Start button again to continue analysis of activated measurements.
4.5 Disruption of Measurements
Error messages may appear if a sample can’t be run. For example:
 If a Cedex Sample Cup is not available in its position on the Multi Sample Tray during measurements, then
the No Cup message will appear.
 If the Multi Sample Tray is not inserted or not inserted correctly, then the Tray not inserted message will
appear.
Some errors may block the analysis of the rest of the measurements. The level of error that should stop the
analysis of all samples can be determined using the Error Level drop-down list at the top of the Multi Run
window. The options for the level of error that will stop the analysis are:
 Fatal: Only errors involving a system / hardware crash, when functionality is not available, will stop analysis.
 Critical: Data loss or any other error that results in an invalid measurement will stop the analysis.
 Error: Errors that do not result in an invalid measurement will stop the analysis.
 Warning: Warning messages with information for the user will stop the analysis.
 Message: Any message will stop the analysis.
