These two Smath documents should help disambiguate literature.
1. Interesting to know about the fixed points.
2. If you are in that trade: helpful mV/I user calibration.
3. Nothing in there about above industrial common temperatures [Pyrometers ...]
4. Pt100 is a much different measuring device.
5. CY7 is not supported by fixed points.
