Introduction

SE322 for Sound Level Meter  is a program for loading the data from the memory of meter or collecting real time data from meter which is connected with a PC or notebook. One may process these data with graphic or text style interface. The program is very easy to use via the graphic user interface. The users do not have to search the function within a lot of menus. The major functions are all in the main window and they are indicated with large icons.

System Required:

  XP/ Windows NT/Vista 32bit.

Minimum Hardware Required:

   PC or laptop with 900 MHz CPU or higher

   256 MB RAM ;

   At least 5 MB byte hard disk space available to install SE322 software.

   Recommended display resolution 800X600 with High Color(16 bit).

 

Tutorial - Quick Start to Use SE322

 

1.Recording real time data in waveform.

  1.Power on the Sound Level Meter first and connect it to a  PC RS-232 serial port wit the cable(SE-300),

  2.Start SE322 program.

  3.If the connection is successful the panel will display the same value as the Sound Level Meter. If fail to connect the meter with PC, it will display "No Connection" on the panel window in TestLink Se322.

                             

 

  4.Select sampling rate from Real-Time Graph window

                       

 note:If PC speed is slow , select sampling rate above 0.2 second. And if it is going to sample a large amount data(more than 5000), at least 64 mega bytes ram is recommended to keep PC running in good performance working well.

 

   5.When the connection is successful , click  to start recording real time data and there will be a waveform on the Real Time Graph Window.

 

  5.Click  to start recording .

 

2.How to save the recorded real time data to a file ?

Click the graph window you want to save and the graph window  will become  active , then choose File | Save from main menu or click  from the tool bar .

 

2. There will be a save dialog window for you to choose the file name and file type to save.There are three types of file name you can choose, binary file(*.ghf), text file(*.txt) and EXCEL format file(*.csv). The *.ghf file use much fewer disk space to save the data than the other two file format, but it can only be used in TestLink SE322. Text file can be opened by TestLink SE322 and any other word processor program like word, notepad etc. EXCEL format file can be opened by  TestLink SE322 and  Microsoft EXCEL.

 

(note. If decimal separator is comma in your country, this file format will be disabled, because .CSV file also use comma to be data separator. for example 78,6 db will become 78db and 6 db in EXCEL )

 

3.How to load the recorded data from the memory of Sound Level Meter and save it to a file ?

(Only for  the model with Data Logger)

 

1. Power on the Sound Level Meter.

2. Press the REC button of the meter to start recording data .

 

3. After a while, press REC button again to stop recording data.

4. Connect the Sound Level Meter to PC

5. Start SE322 program.

6. Choose Data Logger from main menu or click  from tool bar.

 

7.In reference to Data Logger , see DataLogger

DataLogger

           

        When you have Sound Level  DATA LOGGER meter connected to PC and select "DataLogger" from main menu or click

 from tool bar to load recoreded data from the meter and there will be a progress indicator to show the loading progress.if  error occurs, just click "DataLogger" again.

for examples:

                  

         It will transfer first data set to grah and tabule on the right hand side every time after you load recorded data from the Sound Level Meter  and you can click at any data set to change the set for graph.

         On the right hand side is the waveform graph and statistic of the data set you choose. In reference to graph, see Graph . 

     

Graph

 

There are two vertical line (CURSOR A and CURSOR B)in the graph. There are time and value display on top and right side of each cursor.  You can move mouse cursor over  cursor A or B  and click to drag cursor to move left or right. Right below cursor A and B is a slider. You can also click and drag slider to move cursor A or B.

Frequently Asked Question

 

1.I had connected Sound Level Meter to PC serial port and turned meter power on, but it still show "NO CONNECTION".

Answer: It could be that all  serial port are occupied by other application, close all other application . If it still don't work. Restart your computer and run TestLink SE322 again. When program start, it will search automatically from COM1 to COM4 to check connected sound level meter. You can check the connection status from main window like the figure below, for example,the graph below means Com1, Com2 and Com4 are available to this PC and sound level meter is connected to Com2. You can manually change to another COM port when you find out that program can not find the correct COM port which sound level meter is connected to.

 

    

 

2. How can I save the graph to a file which can be used in  EXCEL ?

Answer: When you  save a graph to a file , the default file format is "*.ghf" and you can select *.csv to save files. CSV is an EXCEL file format.You can open it in EXCEL.

(note. If decimal separator is comma in your country, this file format will be disabled, because .CSV file also use comma to be data separator. for example 78,6 db will become 78db and 6 db in EXCEL )

 

3.How to  uninstall TestLink SE322 ?

Answer:Uninstall TestLink SE322 by launching the Add/Remove Programs applet out of the Control Panel, highlighting the SE322, and clicking on the Add/Remove... push button, then it will remove the SE322 folder and files from your computer.

 

4.Why  loading data fail?

Answer: Usually, when It may cause error when meter is recording  and connects meter with PC at the same time.It is recommended that disconnects the connection before recordingof. Or this may happen by the slow respond from some of  the notebook PC system.

 

5.How to zoom the graph?

Answer: Press the left mouse button and drag the cursor to select the new extents,then release the mouse button.

 

6.When I setup the real time sampling with a fast rate(eg. 0.1 sec),  Some of  the sampling data might be lost.

Answer: THis might be caused by slow response time of the PC interface. For better result, the user may close the panel window  or select a slower rate.

 

7.How to print graph with statistic?

Answer: User can copy the graph and statistic to a editor(ex.MS Wrod) separately. Click the  button from the tool bar of graph window to display the customization dialog.Click the Export button from the bottom of the customization dialog.Export dialog will show up. From the Export destination panel, select the Clipboard. Click the Export button from the bottom right of the Export dialog, then the image has been copied to clipboard. Paste this to the editor you are running. Click the  to copy the statistic to clipboard, then paste it to the editor.
