Hi. I'm pretty new to LabView so please excuse my inexperience. I calibrated four thermocouples using a reference thermomister and created each a polynomial curve equation to compensate for the error/difference between the four thermocouples and the reference thermomister. How do I apply these polynomials to the program? Is there an article or example available? I tried searching but not getting a lot of luck.Maybe I'm using the wrong keywords?
Thank you in advance.

typically I create an ini text file where all the calibration coefficients are stored. In my program I read this ini file and place all the values in a cluster that gets passed around in the program to be used. Another option would be to take the calibration cluster and put it into a global variable. Now when you read a value from your thermocouple you pull the appropriate calibration values and calculate what the real value is.
As an example:
y = mx + b
m -> slope calibration value
b -> offset calibration value
You would have to do this calculation for every data point that you want to record.
Hopefully this helps some.

Thank you, JGar! I'll look into that.
