Initial Operation
Measpeak Sorting
The selection of peak/peaks dictates which region in the signal is used for the thickness measurement.
Switch to material selection by going to Settings > Data recording.
Switch to the chart type FFT.
Choose between First peak and Highest peak.
IMS5420 and IMS5420IP67
Layer 1
The MS5420 and IMS5420IP67 evaluates one layer.
The peak in the FFT signal already corresponds to the
thickness. It is not necessary to decide between the first
and highest peak.

Evaluation starts with the first peak, e.g. 3 out of 4 peaks
The IMS5420MP and IMS5420IP67MP evaluates up to five layers.
Each peak represents a thickness value. The peaks are counted
starting at the start of the measuring range (for the thinnest layer)
toward the end of the measuring range (for the thickest layer).
Combined thicknesses of adjacent layers are also evaluated.
