8.1.4.4.1 Entering Times and Values
Time to start Readings:
Enter the total time in seconds for the first absorbance reading.
Time between Readings:
Enter the total time in seconds after the first absorbance reading, for the
second absorbance reading.
Repetition:
Enter a minimum concentration value, below which the Autoanalyzer will repeat the test
under identical sample and reagent(s) conditions, and will show that this result has been repeated.
Linear Limit:
Enter the upper linearity limit provided by the reagent manufacturer. If this value is
exceeded, the instrument will dilute the sample to obtain a value within the linear range. The
instrument will run the dilution using half the sample volume programmed in the
General
tab. The
software will show that the sample has been diluted. The result will be calculated using a dilution factor
for compensation. If the new result is still not within the programmed values, the sample will be diluted
again until the minimum volume indicated in the
Advanced
tab is used.
