keypad will appear so that you can enter a name for the export file. Entering the desired
name and confirming by pressing Enter will save the special method to the external memory.
The method can then be imported into a photometer of the same type.
Press the icon to edit the selected special method. A window will open with the
properties of the special method (see section 5.4.2.2). These can be viewed or changed.
Afterwards, press the icon to confirm and save the changes. Press the icon to
remove the selected method from the list. A dialogue box will open asking you to confirm the
deletion. After confirmi
ng with “Yes,” the method will be removed permanently from the list of
special methods. To run a method, select the appropriate entry from the list and confirm with
.
5.4.2.2 Design
The design menu allows you to create special methods based on previously established
method information, such as factors and wavelengths of the measurement. In the single
wavelength mode, the measurements are carried out at a defined wavelength. The multi-
wavelength mode allows measurements to be made while taking into account (sum,
difference and ratio) of several absorbance values that were measured at up to four different
wavelengths. A calibration function to the fourth degree can be shown. Pressing the icon
opens a pop-up window for selecting a single wavelength method or a multi-wavelength
method (see Figure 30).
Figure 30: Selection of the method design
Depending on which selection is made, a window will open in which the data of the special
method can be entered. In the case of the multi-wavelength method (see Figure 32), not only
the wavelengths of the measurement are requested, but also the factors for the multiplication
and corresponding calculation formula.
