3. To save the data, select
Yes.
4. Evaluate the results:
• 17 cuvette cells are in each cuvette set. Replace cuvette sets when 4 or more cells
in a set are flagged abnormal.
NOTE
An abnormal cuvette is defined as any cuvette with an H, L, or N flag.
• If all the cells fail, replace the lamp.
5. If required, reprint the results.
6. Retain the statistical results and abnormal cell blank list printout with laboratory
records.
Cell blank measurement results
Printed data
The printed data is the OD (optical density) value X 1000. Each cell has two values and a
mean value.
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.
