2.Start SE378 program.

3.If the connection is successful the panel will display the same value as the 4 Channel Thermometer. If fail to connect the meter with PC, it will display "No Connection" on the panel window in TestLink SE378.

4.Select sampling rate from Real-Time Graph window

note:If PC speed is slow , select sampling rate above 1 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 “Real Time | run” or from main menu to start recording real time data and there will be a waveform on the Real Time Graph Window.

6.Click “Real Time | Stop” or to stop recording .

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

1.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 SE378. Text file can be opened by TestLink SE378 and any other word processor program like word, notepad etc. EXCEL format file can be opened by TestLink SE378 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 will become 78 and 6 in EXCEL )

3.How to load the recorded data from the memory of 4 Channel Thermometer and save it to a file?

(Only for the model with Data Logger)

1. Power on the 4 Channel Thermometer.

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

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

### Frequently Asked Question

1.I had connected 4 Channel Thermometer 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 SE378 again. When program start, it will search automatically from COM1 to COM4 to check connected 4 Channel Thermometer. 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 4 Channel Thermometer 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 4 Channel Thermometer is connected to.
