Real Time Data Recording

1. Recording real time data in waveform:

1.1. Power on the Sound Level Meter and connect it to your computer via a micro USB cable.

1.2. Start SE323 application.

1.3. If the connection is successful, the Control Panel will display the same value as the Sound Level Meter. If fail to establish the connection, it will display "No Connection" on the Control Panel.

1.4. Select sampling rate from RealTime Graph window

Note:

If your computer speed is slow, select sampling rate above 2.0 seconds.

If you intend to sample a large amount data (more than 5000), at least 64 MB ram is recommended to keep computer performance.

1.5. Click to start recording real time data. There will be a waveform on the RealTime Graph window.

1.6. Click to stop recording.

2. Save the recorded real time data to a file:

2.1. Click the RealTime Graph window you want to save and the graph window will become active.

2.2. Click to save data to a file.

2.3. There will be a save dialog window for you to choose the file name and format to save.

There are three file formats you can choose from: (1) binary file (*.ghf), (2) text file (*.txt), (3) CSV file(*.csv).

(1) The *.ghf file occupies much fewer disk space to save the data than the other two file formats, but it can only be opened in SE323.

(2) Text file (*.txt) can be opened in SE323 and any other word processor applications, such as

Microsoft Word, Notepad, etc.

(3) CSV format file (*.csv) can be opened in SE323 as well as Microsoft Excel or other spreadsheet applications.

Note:

If decimal separator is comma in your country, this file format will be disabled, because .CSV file also use comma as data separator. For example, 78,6 dB will become two separate records of 78dB and 6 dB.

Data Logger

1. Read the user manual of your Sound Level Meter for the instructions of Data Logger settings.

2. Retrieve recorded data from Sound Level Meter:

2.1. Power on the Sound Level Meter.

2.2. Connect the Sound Level Meter to your computer via a Micro USB cable.

2.3. Launch SE323 application.

2.4. Click to load the data.

2.5. There will be a progress indicator to show the loading progress. If error occurs during the progress, click the button again.

2.6. After the data was loaded completely, the left side window will list all the data sets and their detailed information, such as start date, time, recording rate, etc. Click on any data set to see the graphic view on the right side window.

3. Save recorded data into a file.

Refer to “Real Time Data Recording,” section 2.2.

Graph

1. Specify time window:

1.1. There are two vertical lines (CURSOR A and B) in the graph window.

1.2. You can drag the green sliders to move CURSOR A and B in order to specify your time window.

1.3. The time and sound value will display on the topright of each CURSOR A and B.

2. Statistic 1

2.1. Statistic 1 indicate the start time, sampling rate, data number, average, maximum, and minimum of the entire graph.

2.2. Click to show or hide Statistic 1.

3. Statistic 2

3.1. Statistic 2 indicate the maximum, minimum, and average between CURSOR A and B. The data will be updated automatically when CURSOR A or B is changed.

3.2. Click to show or hide Statistic 2.

4. Graph Tools

4.1. Normal cursor.

4.2. Mark a cross sign on the graph.

4.3. Insert annotation on the graph.
