4.9.1 Progress of data storage The window below appears as soon as recording is started (at a specific time on a defined date if the automatic save method has been selected). All information concerning the progress of data storage is shown in this window.

The “REC.” indicator goes green as soon as recording is begun.

Stop recording in progress of selected set(s) of data The right-hand side of the graduated scale indicates the free space on the hard disk. Keep an eye on the amount of free space left on the hard disk during the data storage process, so as to not to saturate the hard disk and lose measurement data. It is possible to interrupt the recording of one or more sets of data by pressing on the corresponding buttons. Data processing and printing out is possible using the data analysis software (see § 5).

4.10 Shutting down the instrument

It is possible to stop the instrument at any time, (after having stopped recording in progress) by pressing: - the “System” button, and then - the “Stop Instrument” button, which calls up a window in which the user is asked to confirm this decision. The user is returned to the “Main menu” starting point. If the user wishes to quit the application: - press the “Quit” button, a window opens in which the user is asked to confirm the decision.

If the command is confirmed, the start-up/shutdown window appears. For the total shutdown of the instrument, refer to § 3.1.

5. ANALYSIS OF SAVED DATA Data analysis is carried out on the software installed on a PC. The C.A 8350 power quality monitor and PC are linked between their respective USB ports. Note: It is possible to export measurement data to the PC for analysis at a later stage, with the C.A 8350 connected or not (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 interface q Installing the analysis software Data analysis is carried out on the C.A 8350’s data processing software that was developed with “LabVIEW”. - Put the CDROM in the PC’s CDROM drive. - Open up the directory “disk” 1 - Click on the file “Setup.exe” and follow the software installation instructions q

Installing the”PC-linq” USB driver - The USB link is controlled by the “PC Linq” driver. - Put the disk supplied in the PC’s disk drive - Open up the “Setup” file and follow the software installation instructions Once 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 8350 and 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 8350’s “Data” file under the PC’s C:\ directory. The data files in the “Data” directory are created with the following structure beforehand: C:\xxx\yyy\zzz xxx = User name yyy = Project name zzz = File name - Launch the processing software and follow the instructions detailed in the following paragraphs.
