Initial Operation
Positioning the Target, Thickness Measurement
The red-light pilot laser supports you in aligning the
sensor to the target during commissioning.
Turn on or off the pilot laser in the menu Settings >
System settings.
Position the target (measurement object) as much
as possible in the mid of the measuring range.
The peak positions remains stable in the FFT signal,
even though the measurement target moves. The peak
position depends on the target thickness.
