FAQ:
Q: What is the difference between PT100 and PT1000?
A: PT100 reference resistor is 402R, and PT1000 reference resistor is 4.02K.

Q: What is the temperature measurement range?
A: The measurement range is -200 to 550°C.

Q: What is the accuracy?
A: Used with a class A sensor, the absolute accuracy is 0.5 degrees (without calibration). The noise peak-to-peak is 0.093 degrees and the resolution is 0.03 degrees when there is the highest update rate and it is not digitally filtered.
