Error Detection Limits
Mean deviation is a measure of noise in the read window.
Initial Rate High and Substrate Depletion
The initial rate parameter specifies maximum rate of absorbance change measured within the first
cycle after the last component (sample or reagent) is added. When this value is exceeded, results
are suppressed and flagged
Initial Rate High (INIT RATE HI).
The delta absorbance specifies the maximum acceptable difference between the Reaction HIGH
ABS, measured just after sample or starter reagent addition, and the final absorbance measured at
the end of the reaction read window. When this value is exceeded, results are suppressed and
flagged
Substrate Depletion
(SUB DEPL).
Multipoint Spans
Multipoint span limits specify the allowable difference in absorbance or rate between respective
multipoint calibrator levels:
•
1 and 2
•
2 and 3
•
3 and 4
•
4 and 5
•
5 and 6
•
6 and 1
Values are only shown for the number of calibrators specified under "# of Calibrators". A change in
calibrator number resets the spans to zero (0.000).
The sign (positive or negative) of multipoint spans are dependent upon the direction of change
between two successive calibrators. For example, if the response for Cal 2 data < Cal 1 data, the
multipoint span must be negative.
