Communication with a PC

Users can transfer data from the built-in memory on the instrument to a PC through SE376 software. The communication requires a USB or RS-232 serial connection.

Testlink SE376 Software

The SE376 package contains:

• 80mm CD
• Custom-designed USB cable for SE376

System Required:

• Windows NT 4.0/NT2000/XP/Vista/Windows 7

Minimum Hardware Required:

• PC or NoteBook with Pentium 800MHz or higher, 128 MB RAM
• At least 50 MB hard disk space available to install SE376
• Recommended screen resolution 1024×768 or above

Install SE376 and USB-120 connector driver:

1. We recommend closing all other applications before installing SE376.
2. Insert setup CD disk to CD disk drive to display install screen. You may also run MainSetup.exe in the directory of the CD.
3. Click install to begin installation.
4. It will install USB-120 connector driver first:
5. While installing, it will show the window below, just click “next” to continue. (see Fig. 1)
6. Select “Launch the CP210x VCP Driver Installer” option, and then click Finish. (see Fig. 2)
7. Click Install.
8. After you’ve finished installing the USB-120 connector driver, it will install SE376 software automatically. It will copy SE376.exe (executable file) and help the file to your hard disk (default is C:\program_files\SE376.
9. After you’ve finished installation, plug the USB-120 connector into PC USB port, execute.
10. “start” –> “My Computer”, then choose “View System Information” on the left top of the window, the window below will show up.
11. Choose “Hardware” option and click “Device Manager” button, click “+” symbol on the left side of the Ports (COM & LPT), if the device “CP2101 USB to UART Bridge Controller (COMx)” is in the list, the connector is ready to work.

Main menu and buttons:

• Option:  Setup dialog to set attributions of graph. (You may also double click on the graph.)
• Sampling Rate:  Time interval between each data to be recorded. If you want to change it, move your cursor to the digit you want to change and click, then input the new sampling rate. The change will be effective immediately. It will keep up to 5000 data points, when data points exceed this limit, the oldest 100 points will be replaced sequentially.

Real Time Graph

You can zoom this graph by using the mouse:

To Zoom:

1. Press and hold the Shift key.
2. Press the left mouse button and drag the cursor to select the new frame.
3. Release the mouse button.

To Undo the Zoom

• Press the Alt+U keys or click Undo Zoom button.

Note: Zooming method is not allowed in Real Time Graph Window.

Table:

• The table window can be used to record real time data in a table format.
• The maximum number of records that the tabular window can keep will depend on the available memory and hard disk space on your computer.

Data Logger

• When you have the thermometer connected to the computer, select “Load Data” recorded from the thermometer. There will be a progress indicator to show the loading progress.
• If the error occurs, just click “Load Data” again.
• After the data has been successfully loaded to the computer, the left side window shows how many data sets were loaded and their detailed information (start date, start time, recording rate and record numbers). See next page for example.

For example:

• It will transfer the first data set to the graph and tabular on the right side window once you finish loading recorded data from the thermometer.
• You can click on any data set to show its graph and table on the right side window.
• You can choose a rectangular area on the graph to zoom in for detail.
• The vertical dash line in the graph will match the highlight row in the table. When clicking on another row in the table, the vertical dash line will move to the corresponding position to match the time.

Frequently Asked Questions

• Q: I have connected the thermometer to the computer serial port and turned it on, but it still shows “NO CONNECTION”?
  • A: This may be because all your serial ports are occupied by other applications. Close all applications, restart your computer, and run SE376 again.
• Q: In the Table window, I saved a file. Can I use EXCEL to open this file?
  • A: If the decimal separator is a comma (,) in your area, you cannot use the CSV file because the CSV file uses a comma to separate data. This will cause confusion (for example: 23, 6, C, 24.6, C). However, you can use TXT files instead. It uses a tab to separate to data. (for example: 23.6 C 24.6 C) and it will be accepted in EXCEL.
• Q: How do you uninstall SE376?
  • A: Uninstall SE376 by launching the Add/Remove Programs applet out of the Control Panel, highlighting SE376, and clicking on the Add/Remove…button, it will then remove the SE376 folder and files from your computer.
