Temperature Calibration ?

Temperture Calibration ?

With the NI-9217 Modul and Signal Express + 4 PT100 sensors data have been recordered in a climate Chamber of -30 degrees Celsius to 60 degees Celsius withtout calibration. The data were compared to a reference temperature. How can the data be calibrated i.e. about a polynomial. With the calibrated data I want the offset + gain correctet in my Lab View VI.

Exempel:

Ref. Temp: -29.4  Data : -29.9

                   -0.9               0.7

                    21.0             21.3

                    40.8             42.2

                    60.6             62.9
