Working thermometers are then calibrated against the
standard thermometers, following various kinds of calibration
procedures. A typical calibration system is composed
of two processes; the hardware and the software procedures.
There are many useful reports on the hardware
procedure2,3. Here the software procedure, including calibration
point temperatures, interpolation functions and fitting
accuracy, is discussed. In particular, this report focuses
on deducing optimum calibration procedures applicable to
any kind of temperature sensor.
