%X Thermocouples are temperature sensors widely used, but the reliability of the values indicated by themmust be constantly checked. When the tolerable error limits are exceeded or when one wishes to increase thereliability of results, calibration should be performed. This text will address what are the main sources of errorsin thermocouples and what are the ways to calibrate them. By a calibration, it was performed an improvement inLDA Arduino software, which now includes the Equation of a fitting curve in your source code, sendinginformation to the system Lorscheiter Viewer correlated with a measuring instrument calibrated by a certifiedlaboratory.
