Basic Settings Configuration
In order the CHRocodile CLS to be operational for startup some basic parameters should be set up.
Basic setting configuration consists in selection of:
•
Measuring Range: The CHRocodile CLS could accept 5 calibration tables, and each
calibration table corresponds to a unique Optical Head. Consequently, depending on the
Optical Head which is mounted on the CHRocodile CLS unit, the operator must select the right
Measuring Range or Calibration Table. (Cf. command $TABL in section 5.2)
•
Measuring Mode: The CHRocodile CLS has two measuring mode: Altitude and Thickness
measurement. Depending on the application, operator must select the right Measuring Mode.
(Cf. command $MOD in section 5.2)
•
LED Intensity Level: The LED intensity Level can be adjusted from 0 to 100%. As for
Measuring Rate, this adjustment essentially depends on object reflectivity. Adjust LED
intensity in order to obtain a high signal intensity on the 192 channels of the line sensor. The
goal is to obtain the higher intensity without saturation. On homogeneous target, each
channel’s intensity is mostly the same, this is not the case on inhomogeneous target and in
that case, it is recommended to adjust intensity in order to obtain the maximum intensity close
to saturation. In order to adjust LED intensity, use the LAI command or the equivalent .NET
DLL function (Cf. sections 5.2 and 5.4).
•
Measuring Rate: Instead of adjusting intensity, it is also possible to adjust the measuring rate.
The Measuring Rate is related to data transmission frequency. The CHRocodile CLS
maximum measuring rate is 2KHz. The higher the Measuring Rate is the lower the signal
intensity is. Consequently, depending on the object reflectivity under measurement, the
Measuring Rate (measuring frequency) must be adjusted in order to remove saturation or too
low intensity signal. In order to adjust measuring frequency, use the SHZ command or the
equivalent .NET DLL function (Cf. sections 5.2 and 5.4).

Data measurement Training
When mechanical interfacing is done, the object to be measured must be positioned inside the
measuring range of the CHRocodile CLS.
This procedure is valid for Altitude and Thickness mode, i.e. to perform topographic measurement on
reflecting object or to perform thickness measurement on transparent object.
Measuring Altitude procedure consists in:
