(see 3.1.2).

q Recommended PC configuration- Operating system: Windows 98 or 2000- Processor: Intel Pentium II 350 MHz or above- Memory: 128 MB min- Hard disk: 4 GB min- USB interfaceq Installing the analysis softwareData analysis is carried out on the C.A 8350s data processing software that was developed with LabVIEW.- Put the CDROM in the PCs CDROM drive.- Open up the directory disk 1- Click on the file Setup.exe and follow the software installation instructions

q Installing thePC-linq USB driver- The USB link is controlled by the PC Linq driver.- Put the disk supplied in the PCs disk drive- Open up the Setup file and follow the software installation instructionsOnce the PC Linq USB driver is installed, click on the Start data transfer button on the start-up screen (see 3.1), the C.A 8350and the PC are then respectively referred to as the Remote and the Control (see 3.1.2).

q Copying measurement files from the C.A 8350 (see 3.1.2)- Copy the C.A 8350s Data file under the PCs C:\ directory.The data files in the Data directory are created with the following structure beforehand:C:\xxx\yyy\zzzxxx = User nameyyy = Project namezzz = File name- Launch the processing software and follow the instructions detailed in the following paragraphs.
