Sorry, for probably sounding rude
Alternative 1.) Use the search engine of your choice, scroll down a bit and you'll find things like https://de.mathworks.com/help/daq/acquire-temperature-data-from-a-thermocouple.html
Alternative 2.) The people at the NI forums are willing to help, yet in order to address the right people, post your question with a related software which in this case would probably be NI Daqmx
Hope that helps
