Here is an example: The data set will be transfered to the graph on the right hand side of the screen, each time after you load your recorded data from the meter. The waveform graph and statistics on the right hand side of the screen displays the information of the data set you have chosen. Therefore, you can click any data sets to the change the data set displayed in the graph. Tutorial - Quick Start to Use SE322 TestLink Recording real time data in waveform 1. First turn the meter on and connect it to a PC RS232 serial port using the cable (SE-300) provided. 2. Start SE322 program. 3. If the connection is successful the panel will display the same value as the Sound Level Meter. If the connection between the meter and the PC has failed, it will display “No Connection” in the panel window in TestLink SE322. 4. 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 stop recording. 1.800.868.7495 [email protected] REED-Direct.ca

Start the SE322 program 6. Choose Data Logger from the main menu or click from tool bar Frequently Asked Questions Question: I connected the meter to a PC serial port and turned meter on, but it still shows “NO CONNECTION”. Answer: It could be that all serial port you’re using is occupied by another applica- tion, close all other applications. If it still don’t work. Restart your computer and run TestLink SE322 again. Question: How can I save the graph to a file which can be used in Microsoft Excel? Answer: When you save a graph to a file, the default file format is *.ghf and you can also select *.csv. CSV is an Microsoft Excel file format. You can then open it using Microsoft Excel. Question: How do I uninstall TestLink SE322? Answer: Launch the Add/Remove Programs applet out of the Control Panel, high- lighting the SE322, and clicking on the Add/Remove button. This will remove the SE322 folder and files from your computer. Question: Why would loading data fail? Answer: This might be caused by the slow response from some of the PC. Question: How do I zoom into the graph? Answer: Left click (click the left mouse button) and drag the cursor to select the new extents and release the mouse button. Question: 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 the slow response from some of the PC. 1.800.868.7495 [email protected] REED-Direct.ca
