AN75511 describes the theory of thermocouple operation and measurement. CE219905 describes how to measure a thermocouple using either a PSoC 3 or PSoC 5LP device. This code example shows how to achieve the high-end accuracy described in AN75511. Specifically, this code example shows how to achieve an accuracy of 0.1% with 0.01 °C precision. This accuracy is achieved through calibration. There are two types of calibration – an initial gain offset calibration and a drift calibration.
