After the data has been loaded, the left hand side of the computer
screen will show how many data sets were loaded as well as the detail
information for each data set: Start Date, Start Time, Recording Rate and
Record Numbers. 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

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

Answer: It could be that all serial port you’re using is occupied by another application, 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 le which can be used in Microsoft Excel?
Answer: When you save a graph to a le, the default le format is *.ghf and you can
also select *.csv. CSV is an Microsoft Excel le 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 les 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.
