function. Max. 7 digits. Unit for the concentration result.
In the preprogrammed methods of the
Routine group, the
selection is restricted to units that are useful for these methods.
Formula type Selection:
division | subtraction Only for the Dual wavelength method group.
Formula type for calculating the absorbances at the two
measurement wavelengths prior to evaluation with factor or
standard.
Formula: a Value input:
Value for
a in the
evaluation formula.
Limit: max. of 5 digits
including decimal
point.
Only for the Dual wavelength method group.
Value for a in the formulas: [(a*A1) / (b*A2)] * c + d and [(a*A1) -
(b*A2)] * c + d.
Formula: b Value input:
Value for
b in the
evaluation formula.
Limit: max. of 5 digits
including decimal
point.
Only for the Dual wavelength method group.
Value for b in the formulas: [(a*A1) / (b*A2)] * c + d and [(a*A1) -
(b*A2)] * c + d.
Formula: c Value input:
Value for
c in the
evaluation formula.
Limit: max. of 5 digits
including decimal
point.
Only for the Dual wavelength method group.
Value for c in the formulas: [(a*A1) / (b*A2)] * c + d and [(a*A1) -
(b*A2)] * c + d.
Formula: d Value input:
Value for
d in the
evaluation formula.
Limit: max. of 5 digits
including decimal
point.
Only for the Dual wavelength method group.
Value for d in the formulas: [(a*A1) / (b*A2)] * c + d and [(a*A1) -
(b*A2)] * c + d.
Calculation Selection:
factor | standard Evaluation procedure for the calculation of the sample
concentration from the measured absorbance.
