2.4.5 Alarm Check Method
(1)
Photometry Assay Calibration Check
(a)
SD check of approximate expression
When SD in the difference between the automatically generated calibration curve
and the measured absorbance value in non-linear calibration is larger than "SD limit
absorbance," comment SD? is printed. SD value is printed under the test name in
the result of calibration. Unless check is desired, input 999.9.
(b)
Duplication check
In measurement of reagent blank and standard solution, comment DUP is printed
when the difference in absorbance between two measurements is larger than
"duplicate limit absorbance." Unless check is desired, input 32000.
(c)
Sensitivity check
When the difference in absorbance between reagent blank (STD1) and standard
solution (having the maximum concentration if there are multiple standard
solutions), comment SENS is printed. Unless check is desired, input 0.
(d)
Standard solution 1 absorbance check
When the absorbance of reagent blank (standard solution 1) exceeds "standard 1
absorbance range," comment S1 ABS is printed. In an end-point assay test, the
absorbance value on the left side of calibration result printout is checked and that
on the right side is checked in a rate-assay test. Unless check is desired, input -
32000 to 32000.
