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 ?~400.00 ?), 0.05 mA~0.8 mA (400.0 ?~1500.0 ?), 0.05 mA~0.4 mA (1500.0 ? ~4000.0 ?), excitation current (0.25 mA for Pt1000 range).
Temperature Coefficient: ?0.05 ?C /?C for measure, ? 0.05 ?C /?C (<18 ?C or >28 ?C) for source.
Supports pulsed transmitters and PLCs with pulse times as short as 5 ms.
