4 Automatic Adjustment and Alignment Verifi cation
The automatic adjustment and verifi cation of alignment adjusts the focus position of the fl ow chamber
and verifi es the alignment of the chamber itself to ensure that images of consistent quality are taken during
measurements.
The service technician will carry out a focus adjustment before the initial operation of the Cedex HiRes Analyzer.
The focus adjustment is always necessary after the Analyzer has been moved. Additionally, we recommend
running a focus adjustment once per month for control purposes. Both the white balance and the focus on the
objects to be examined are optimally set during this focus adjustment. The focus adjustment lasts approximately
20 minutes and is done with the Cedex Calibration Beads included in the contents of delivery.
If at all possible, the analyzer should never be turned off. If it is necessary to turn it off, the analyzer needs at
least 2 hours to warm up before an Automatic Adjustment can be carried out.
Proceed as follows to do the focus adjustment:
1
Open the Functions menu in the Control Center’s menu bar.
2
Click on Automatic adjustment to open the Automatic Adjustment and Alignment Verifi cation window.
3
Pipette 1 ml of a well-mixed bead solution (Cedex Calibration Beads) into a Cedex Sample Cup.
4
Attach the Cedex Sample Cup to the sample port or place the Cedex Sample Cup in the DefaultCup position
on the multisample tray (see “
The Multi Sampler DefaultCup”).
5
Click on the Start Automatic Adjustment button. You will be asked to verify that the beads have been
prepared. Click on OK to confi rm and start the adjustment process.
