Changing the position of the carousel
When is this necessary?
It is necessary to change the position of the carousel in the following cases:
 If the analyzer was switched off, the carousel is no longer in zero position. Before you can start
an analysis, you must move the carousel back to zero position.
 If you lose samples, it may be necessary to move the carousel to a different position.
Changing the position
Please observe the following instruction:
Caution Inserting multiple samples into the ball valve (only for
solid operation)
If there are samples in the carousel while you are changing the position of the
carousel via System > Carousel position, multiple samples may fall into the ball
valve at the same time. In this case, a service technician is required.
Before changing the position of the carousel, always remove all samples from the
carousel.
Proceed as follows:
 Remove all samples from the carousel.
 Open the "Set carousel position" dialog via System > Sample Position.
 Once you have removed all samples from the carousel, check the checkbox next to "All samples
removed from carousel".
 Decide:
If you want to...
 ... move the carousel to a position other than zero position, select the radio button next to
"Position" and use the arrows to set the position in the box next to it.
 ... move the carousel to the zero position, select the radiobutton next to "Reference run".
 Click OK. This closes the dialog and moves the carousel to the desired position.
Export analysis data for support
Export for support
The service department can draw conclusions about the condition of the analyzer from the analysis
data, particularly the graphical information. Therefore, analysis data must be exported in mdb format
for support, as this also contains graphical data.
