witch to material selection by going
S
to Settings > Data recording.
Assign the materials to the individual
layers according to the target used.
Compared to the example on the left, the
thickness of the middle layer (blue) has
increased and is greater than the top and
bottom layers. The material selection must
be adjusted for this case.
In the FFT signal, peak 1 up to peak 3
change places, see Chap. Measpeak
Sorting.
The material selection for a thickness
measurement starts with the thinnest layer
(layer 1) independent of the physical ar-
rangement in the measuring object.
1) The IMS5420MP and IMS5420IP67MP
controllers also evaluate combined
thicknesses of different layers. A material
does not necessarily have to be selected
for layer 4. Peak 4 stands for a combi-
nation layer of the two upper layers. The
controller evaluates this layer; however,
the result has no significance in the
measurement.
