In case of a complex layer (mixture of materials or alloy) enter more elements and their percent-
ages.
9. Click Elem.+ to transfer the values to the display field.
The values of the entered layer appear in the large display field.
10.Repeat steps 8 to 9 for each element of the current layer.
11.Click OK to finish the value entry for the current layer and to save the data.
The window Definition of Elements New Layer disappears. The values of the layer appear in
the large display field of the window Definition of measuring conditions….
12.Repeat steps 4 to 11 for each layer of the coating system until all layers are entered.
Enter the base material (substrate material) like another layer with the following options:
a In the area Thickness check the option The thickness of the layer is fixed (known) .
b Check the option Massive (Sat.)
13.Click OK to close the window Definition of measuring conditions… .
What you can do next
You can enter compensation spectra, see Chap. 16.3 on Page 129.
