15.  Learning to Use TestLink Se322 

 

a)  Recording real-time data in waveform 

 
1.  Activate the DVM322DI and connect it to a PC RS-232 serial port with the supplied cable. 

2. Start the program. 
3.  The panel will display the same value as the DVM322DI itself if the connection is successful. The message “No 

Connection” is displayed on your computer screen in TestLink Se322 if the connection has failed. 

4.  When the connection is successful, click   to start recording real-time data. The corresponding waveform is 

displayed in the real-time graph window. 

5. Click   to start recording. 
 

b)  Hoe bewaar ik de opgenomen real-time data in een file? 

 
1.  Klik het grafisch venster aan dat u wilt bewaren. Het venster wordt nu actief. Selecteer “File” 

 “Save” in het 

hoofdmenu of klik op het  -icoon op de toolbar. 

2.  Vervolgens verschijnt er een dialoogvenster waarin u de naam van de file en de extensie kunt ingeven. U kunt 

kiezen uit drie verschillende bestandsformaten : binair formaat (*.ghf), text file (*.txt) en EXCEL formaat (*.csv). 
Voor een *.ghf file heft u veel minder vrije ruimte nodig op de disk dan voor de andere twee formaten, maar u kunt 
dit type enkel gebruiken in TestLink Se322. Met TestLink Se322 en met om het even welke andere 
tekstverwerker kunt u text files openen. Het EXCEL formaat is compatibel met TestLink Se322 en Microsoft 

Excel. 

 
 

b)  How to save the recorded real-time data to a file. 

 
1.  Click on the graph window you want to save to make it active, then choose “File” 

 “Save” from the main menu or 

click   on the toolbar. 

2.  There will be a dialogue window where you can enter the file name and the extension. Three types of file name 

can be used : binary file (*.ghf), text file (*.txt) and EXCEL format file (*.csv). A *.ghf file uses much less disk 
space than the other two file formats, but it can only be used in TestLink Se322. TestLink Se322 and any other 
word processor program can open txt. files. e word, notepad, etc. An Excel file is compatible with TestLink Se322 
and Microsoft Excel.
