Fft Signal Check; Signal Quality - MICRO-EPSILON interferoMETER IMS5400-DS Quick Manual

Initial Operation

FFT Signal Check

Go to the Measurement chart
menu. Show FFT signal display
with FFT. The signal in the chart
window shows the distance be-
tween sensor and target or the
target thickness. Left 0 % (small
distance) and right 100 % (large
distance). The corresponding
measured value is marked by
a vertical line (peak marking).
The diagram starts automatically
when the website is called.

Signal Quality

A good measurement result can be achieved with sufficient FFT signal intensity. Reducing the measuring rate enables
longer exposure of the CCD array, therefore leading to high measurement quality.
Go to the menu Home >
Signal quality and adapt
the measurement dynamics to
the requirements. Check the
result in the FFT signal.
