Usable Result Range
Usable result range specifies the analytical range of the reagent. Results are suppressed and flagged
as out-of-instrument range low (OIR-LO) or out-of-instrument range high (OIR-HI), respectively, if
these ranges are exceeded.
If any parameter is edited, the instrument automatically changes the Reportable Range information
from System Setup to the Usable Range defined for the UDR. The Reportable Range must be re-
entered if the values are different from the Usable Range.
Error Detection Limits
Reagent Blank (Absorbance or Rate)
Reagent blank specifies the minimum and maximum absorbance or rate (method dependent) for
the reagent blank measured during the blank read window. If these values are exceeded, the results
are suppressed and flagged as blank absorbance/rate high (BL ABS HI or BL RATE HI) or blank
absorbance/rate low (BL ABS LO or BL RATE LO).
Mean deviation is a measure of noise in the read window.
Reaction (Absorbance or Rate)
Reaction specifies the minimum and maximum absorbance or rate (method dependent) measured
during the reaction read window.
•
For upgoing rate or endpoint reactions, if the reaction absorbance is less than the Low Limit
then results are suppressed and flagged as RX ABS LO. Likewise, if the High Limit is exceeded,
the result is suppressed and flagged RX ABS HI.
•
For downgoing rate methods, the Low Limit indicates the maximum rate observed during the
reaction read window.
•
For downgoing endpoint methods, the Low Limit indicates the maximum absorbance observed
during the reaction read window.
