Standard Operations
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 the
stored factors.
In addition, measured values 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. Cuvette/vial
errors and soiling are recognized and highly precise results are
obtained.
5.5.1 Complete a barcode 13 mm test/vial
1. Insert the light shield in cell compartment #2.
2. Prepare the barcode 13 mm cuvette/vial in accordance with the
working procedure and insert the cuvette/vial in cell
compartment #1.
• When a coded cuvette/vial is placed in cell compartment #1
(
Figure 11 ), the corresponding measurement program is
automatically activated in the Main Menu.
