Measurement Software Analysis II - Calibration and Curve Fitting

In this lab, students will learn about the need for calibration and the different sensor properties that lead to different calibration types. Furthermore, students will experiment with thermocouple measurements and voltage-temperature curve fitting and to verify the coefficients of a K-type thermocouple using a simulated data set.

This is lab 12 of 17 in the course, Measurements and Instrumentation.


After completing this lab, students will be able to:
  1. Explore the differences between calibration types and understand their uses
  2. Use the Thermocouple Input embedded in your NI Automated Measurements Board to do a Two-Point Calibration to get accurate temperature readings from a thermocouple sensor
  3. Experiment with polynomial curve fitting and implement a curve fit
