can be entered.  

 

Zero link:

 When the "Barcode link" option is used, the "Zero link" option is enabled. When the 

corresponding test is selected, the zero stored for the MACHEREY-NAGEL tube test will be 
used  for  the  calculation.  This  allows  a  measurement  without  a  zero  solution.  This  option  is 
available only for the test which was selected in the context of the barcode link and for which 
a zero is already stored in the photometer.  

 

Cuvette size:

 Select the cuvette size from the displayed list box. When methods are carried 

out, the photometer detects automatically whether the correct cuvette is being used.  

 

Formula:

 The formula field is where the factors for the final calculation of the measurement 

result  are  entered.  Formulas  to  the  4th  degree  can  be  entered.  Tapping  on  the  individual 
fields  will  open  a  numeric  keypad  for  entering  numerical  values

.

  Negative  factors  can  be 

depicted by entering a minus sign before the numeric value. 

 

Please note: The formula has the format y = F0 + F1*E + F2*E

2

 + F3*E

3

 + F4*E

4

 with E as 

absorbance value and F as factors of the equation. The factors are input as an equation, as 
determined by a plot of concentration values (x-axis) against the absorbance values (y-axis).  

 

After successfully entering all parameters, confirm the entries with 

 . The method will be 

saved and included in the list of user methods (see section 5.4.2.1). The properties that were 

entered can be edited there via the 

 icon. A report on the special method properties and 

data  can  be  printed  by  pressing  the 

  icon  and  selecting  "Print."  The  entries  "Export  to 

PNG  file"  and  "Export  to  CSV  file"  allow  the  method  report  to  be  exported  to  a  connected 
storage medium.  

5.4.2.3 

Calibration 

The  Calibration menu  is opened  by  pressing  the 

  icon.  This  menu is  used  to  determine 

absorbance values for standard solutions of known concentrations as part of creating a user-
defined special method (see Figure 34).
