Stopping continuous analysis
When do I stop continuous analysis?
It makes sense to stop a continuous analysis in the following cases:

If the result of the blank value indicates that the instrument is leaky.

If the results of the conditioning sample indicate that parts of the instrument are defective or that
gas pressure and flow behaviors are not OK.

If results of the daily factor deviate substantially from the last results.
Stopping a continuous analysis spontaneously
Proceed as follows:

Execute the command
System > Single run
in the operating software.

This stops the analysis after measuring the current sample.
Moving a stop marker
The program automatically moves the stop marker to the last sample position during sample data
input. It is therefore only necessary to move the stop marker in special cases.
Nevertheless, if for any reason you have to move the stop marker proceed as follows:

Open the "Set stop marker" dialog by selecting
Edit > Stop tag
.

Use the arrow buttons to set the sample number at which to set a stop marker.

Click
OK
. This closes the dialog and moves the stop marker to the desired position.
Re-weighing after sample loss
Sample loss
If you drop a sample on the floor when loading the carousel, for example, the sample is contaminated
and should not be analyzed. You have to prepare and weigh a new sample.
Re-weighing after sample loss
Proceed as follows:

Prepare the sample again.

Open the "Set current weight" dialog by selecting
Edit > Current weight
.

Use the arrows to specify the sample to re-weigh.

Click
OK
. This closes the dialog and the cursor moves to the "Weight" column of the selected
sample number.

If 21 CFR Part 11 functionality is enabled, the "Comment change" dialog is displayed. Enter a
justification in the "Comment modification" dialog and click
Close
.

Weigh the sample If the weight is not transmitted online, enter the weight by hand in the sample
view on the PC.

Insert the new sample on the carousel.

Open the "Set current weigt" dialog again by selecting
Edit > Current weight
.

Use the arrows to set the number following the number of the last sample.

Click
OK
. This closes the dialog and the cursor moves to the "Weight" column of the selected
sample number.
