5.5 Barcode Programs
A special barcode reader in cell compartment #1 automatically
reads the barcode on the 13 mm cuvette/vial as the cuvette/vial
completes a single rotation. The instrument uses the barcode
identification to automatically set the correct wavelength for the
analysis and calculates the result immediately with the help of
stored factors.
In addition, readings are recorded at 10 different positions during
a rotation. A special outlier-elimination program is run and then
the average of the measured values is calculated. Cell and round
cell faults and contaminations are detected and therefore a very
precise result is determined.
5.5.1 Perform a barcode test
1. Prepare the barcode test in accordance with the work
instruction and insert the cell into the cell compartment (1).
• When a coded cell is inserted into the cell compartment
(1) (
Figure 3, Page 19 ), the corresponding measurement
program is automatically activated in the main menu.
• Otherwise select in the main menu the menu option
Barcode Programs and insert a zero cell (depending on
work instruction) into the cell compartment (1).
Note: To obtain further information on the Help Guide ("Information"
symbol), refer to
Appendix A, Page 151 .
The measurement is started automatically and the results are
shown.
Note: To define a sample dilution, press the Dilution key in the toolbar.
To evaluate other cell tests and other parameters insert the
prepared cell into the cell compartment and read off the result.
Note: The control bar, which is shown on the right on the display, shows
the relationship of the measurement result with the measurement range.
The blue bar shows the reading result independently of any dilution
factor that was entered.
