Notes:
Sensor inaccuracies not included.
Resolution: 0.1 °C.
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), 0.4 °C (Other RTD types) to the specifications.
Source Accuracy in source mode is based on 0.5 mA~3 mA (1.00 Ω~400.00 Ω), 0.05 mA~0.8 mA
(400.0 Ω~1500.0 Ω), 0.05 mA~0.4 mA (1500.0 Ω ~4000.0 Ω), excitation current (0.25 mA for Pt1000 range).
Temperature Coefficient: ±0.05 °C /°C (<18 °C or >28 °C) for both measure and source.
Supports pulsed transmitters and PLCs with pulse times as short as 5 ms.
