Can we measure a thermocouple and a voltage at the same time?

[Sully61]

I am a student studying superconductors with limited knowledge of LabView. I have figured out how to measure two voltages using a DAQ board but what I am having trouble with is designing a program that can measure a voltage and a thermocouple at the same time. If anyone could give some suggestions within one to two weeks I would appreciate it.

I am also having trouble saving the data to a text file. I would like to save the data from the start of the experiment instead of at the end only. If anyone has any suggestions about that they too will be greatly appreciated.

Thanks,
Gary

Hi Sully61,

Welcome to the forums. Basically, you are using the hardware resource to acquire a voltage and the driver is converting it to a thermocouple unit. The simples way to have them both is to acquire the voltage and then there is a LabVIEW function called "Convert Thermocouple Reading.vi" that will do the conversion work for you.

Now to save it into text file there are way many possibilities. If you are not very familiar with files in general, I would use the Express VI called "Write to Measurement File" which is very straight forward. Just select the format to text (lvm) and change the extension to txt (if you want). If you are more advance with text files and have programmed before in other environments, you can modify the shipped example called "Write to Text File.vi" which contains low level file functions for efficient data storage.
Hope this information helps,
