- Then, check and store the raw signal (this file could be demanded by PRECITEC technical
support team). The raw signal should show a peak for channels which contribute to the
measurement.
Case 2: The target is positioned in front of the sensor, and distance measurement is valid only for
some channels:
- Set the measuring frequency to minimum ($SHZ100 or equivalent .NET DLL function).
- Set the LED intensity to maximum ($LAI100 or equivalent .NET DLL function).
- Check if the sample topography variations along the line are fitting with optical head
measuring range; i.e. - Peak to Valley altitude variation should be less than measuring range -
, - maximum local slope on target should be less than maximum measuring slope -, - target is
not homogeneous and show high reflectivity variations along the line -
- Set a mirror in place of your target and store the raw signal for each channels (this file could
be demanded by PRECITEC technical support team).
8.4 Thickness measurement:
Case 1: The target is positioned in front of the sensor, and no thickness measurement is collected for
all channels.
- Check that the target thickness is inside minimal and maximal measuring thickness range,
- Check the target transparency,
- Set the measuring frequency to minimum ($SHZ100 or equivalent .NET DLL function).
- Set the LED intensity to maximum ($LAI100 or equivalent .NET DLL function).
- Check if a white light line emitted from the optical head is focused on the target.
- Check if the two surfaces of the target are inside the measuring range of the 192 channels (Cf.
section 2.9.1).
- Check if the target surface is normal to the optical head axis. The maximum angle between
target surface and optical axis is given by the maximum measurable slope (Cf. section 2.9.1).
- Check if the measuring mode is Thickness mode.
- Check if the Thickness is transmitted ($SODX 17152 or equivalent function),
