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.

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 SE309 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.
2. How can I save the graph to a file which can be used in EXCEL ?
Answer: When you save a graph to a file , the default file format is "*.ghf" and you can select *.csv
to save files. CSV is an EXCEL file format.You can open it in 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 )
