Note:
* Specification valid with an excitation current >0.2 mA (0...400 ohm),
>0.1 mA (400...4000 ohm)
** Read accuracy is based on 4-wire input. For 3-wire RTD
measurements, assuming all three
RTD leads are matched, add 1.0 °C (Pt10 and Cu10), 0.6 °C (Pt50
and Cu50), and 0.4 °C
(Other RTD types) to the specifications.
