Resolution: In the middle range, the best resolution is 0.1 ℃, except for 10 Ω Cu (427). Excluding the inaccuracy of sensors. When measuring with 2-wire and 3-wire RTDs, add 0.4 ℃. When measuring with a thermocouple, external reference junction compensation is used. If internal reference junction compensation is used, add 0.2 ℃.
