(2) Calibration Curve Factor Confirmation screen (Fig. 4-
31) appears. On this screen, calibration curve factor,
correlation coefficient and determination coefficient can
be set. For each parameter (setting item), refer to
Table 4-13.

Parameter Explanation
Curve Factor
Denotes the factor of calibration curve.
A0 and A1 stand for the values expressed by
the following equation.
[When ABS = f(CONC)]
Absorbance = A1 x concent A0
Concentration = (absorbance - A0)/A1
[When CONC = f(ABS)]
Concentration = A1 x abso A0
Correlation Coef.
Used for evaluating the linearity of calibration
curve. When this value is closer to 1.0000,
the linearity can be evaluated to be higher.
Calculation formula is introduced in
Explanation 4-1.
