RTD source in
°
C:
Accuracy is based upon 4W connection, driving voltage is less than 1.7V and the
excitation current is based upon 0.5mA to 5mA (0 to 400
Ω
) and 0.05mA to 5mA
(400
Ω
to 7000
Ω
). For 3-wire RTD source, assuming all three RTD leads are
matched, add 1.0 °C (Pt10 and Cu10), 0.6 °C (Pt50 and Cu50), 0.4 °C (Other
RTD types) to the specifications.
