Each measuring of a standard (calibrator) can be executed as single, double or triple determination.
Following is shown:
•
Each measuring of a standard (calibrator) can be executed as single, double or triple determination.
Following is shown:
In the white reading window the
averaged absorbance of the standard
is shown.
Below the white reading window the
absorbance 1, 2 and 3 of a standard
are shown.
By [OK] the average of all values is
taken over. Values with 0 are ignored
and excluded from the calculation.
The resulting factor is calculated from
the average of the standard.
By [CURS.] a value is selected. A
flashing white square marks the
current value.
By [DEL.] a value is deleted and
excluded from the calculation.
By [RESULT] a measuring is
triggered.

The determined resulting factor of a standard measurement is stored together with the corresponding
method number. After renewed selection of this method the last resulting factor is offered as "OLD
STD".
•
The principle of the multiple measurement can also be expanded to all measurements. The
corresponding entry can be set invoking a basic method. The parameter is definable in prepro-
grammed methods (chapter 6 - METHOD EDITOR).

Fundamental to the methods with multi-standards ...
•
Linear calibration is used in the case of two calibrators. The absorbance forms a linear diagram with
the concentrations (chapter 7.2.2 - Multi-standard functions).
•
Nonlinear calibration is used for samples with a nonlinear but reproducible connection between the
absorbance and the concentrations. At least three (maximum 20) calibrators are required for nonlinear
calibration (chapter 7.2.2 - Multi-standard functions).

Fundamental to bichromatic measurements …
•
The calculation procedures based on endpoint measurement (CP 1 to CP 8, CP 13 and CP 14) can be
executed bichromatic. The zero measurement will be done with a wavelength defined as bichromatic.
The bichromatic wavelength might be not included in the standard set of filters. The bichromatic
wavelength can be set after calling a method (chapter 6 METHOD EDITOR Fig. 6.5).
