Hello,
Thank you for contacting National Instruments.
It is my understanding that you are trying to find a VI that mimics a thermometer within LabVIEW 7.0.
Fortunately, LabVIEW 7.0 has a library of built-in example VIs, several of which deal with temperature analysis. First, open LabVIEW 7.0 and select [Help]>>[Find Examples]. Search for "temperature." Six example VIs will appear. I think the "Temperature System Demo" VI will best suit your needs. Please keep in mind that you can save any of the example VIs under a new name and proceed to customize them for your desired functionality.
I hope this helps. Please let me know if I can further assist you. Have a great day!
Kind Regards,
Joe Des Rosier
