Cleaning The Analyzer And Rack Handler Exterior Panels - Siemens ADVIA 2400 Operator's Manual

Abnormal cuvettes
A list containing abnormal cuvettes is printed as part of the cell blank. The list contains
marks indicating abnormality. Cuvettes on the list are not used for analysis. Abnormal
cuvettes have the following characteristics:
•
Cuvettes exceeding the cell standard value (set in the System Parameters System
window) are marked "H" or "L."
•
Cuvettes exceeding the cell breakup limit value (set in the System Parameters
Settings window) are marked "N."
•
Cuvettes exceeding the skip absorbance value (set in the System Parameters Settings
window) are skipped (marked E), and therefore not used for analysis.
•
Cuvettes exceeding the lamp energy voltage limits are skipped (marked U or D), and
therefore not used for analysis.
•
Abnormal cuvettes remain registered as abnormal until a future measurement
determines that they can be used.
Reference value
The reference value (the average value of the measurements of all cuvettes) remains the
same until the next measurement.
