VI for use with DAQPad 6015 to Measure Thermocouple Temperature

[hot]

I want to continuously measure the temperature of a material using a LabView program (VI), NI DAQPad-6015 (for USB) and a J type thermocouple. The front panel would have a graph of the temperature changes. This means that, I want to be able to see the temperature changes on a real time graph. The acquired temperature data should be saved to a text file so that I can analyze later.

I want the VI to be able to acquire the continuous temperatures of 1 or more different material at a time. This means that, I may choose to record the temperatures of say 3 materials using i3 individual thermocouples connected to the NI DAQPad-6015. 

Where can I find a simple VI to do this task? I tried a couple of examples from NI but I get error messages. Thanks

Hello,

To achieve all the functionality you are looking for in your temperature measurement application you will need to modify a data acquisition example program which you can find by going to Help->Find Examples.

Take a look at 'Cont Acq Thermocouple Samples-Int Clk.vi' to see how to acquire and graph one or more thermocouple channels.  A search for 'thermocouples' should bring this example up in the Example Finder.

To write the data to a text file there are several options   The typical format is a tab-delimited file.  The simplest function to use is the 'Write Spreadsheet File' function in the File I/O section of the functions palette. 

Hope this helps.

Thanks Jennifer, I'll look at the example you pointed out.

By the way, in the future, can I post the a VI or block diagram on this discussion panel for problem clearity?

Yes it is possible and you may attach a VI or a screenshot of your block diagram on the forums.
