Positioning The Target, Distance Measurement - MICRO-EPSILON interferoMETER IMS5400-DS Quick Manual

Initial Operation

Positioning the Target, Distance 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.

Sensor SMR
The LED Range on the controller front indicates the
position of the target in relation to the sensor.

Pilot laser is turned on and

You can also position the sensor using the FFT sig-
nal 1 . The interferometric measuring principle provides
measurement values in front of and behind the actual
measuring range. An incorrect measuring range dis-
tance can be recognized by the running direction of the
peak in the FFT signal. Inverse direction of FFT signal, if
the target is outside measuring range.
