Curve Non-Monotonic check This check determines if the calibration curve is monotonic within the test range.
The Non Mono flag is displayed if the curve is not monotonic within the defined test
range. This flag is also displayed if the calculation model Linear Interpolation is used
and the test range is defined outside the defined standard target value.
Calculation Error check The Calc Error flag is displayed if the calibration curve cannot be calculated.
Curve out of Range check With this check the calibration curve is inspected to make sure it is within preset
limits. This check varies according to the calibration mode.
o With Linear Interpolation, the check is not carried out.
o With Logit/Log4, Logit/Log5, Exponential 5, the check is carried out for each
standard.
Theoretical rate for each expected standard concentration:
Theoretical minimum rate for each expected standard concentration:
Theoretical maximum rate for each expected standard concentration:
Linear Regression This check establishes whether the calibration parameters R
0
and F are within the
accepted range.
The Out of Rng flag is displayed if the check criteria are not met.
Theoretical rate of the standard.
Expected standard concentration.
Theoretical minimum rate of the standard.
Test-specific curve parameters (dependent on the calibration mode).
Theoretical maximum rate of the standard.
