1. Sensor inaccuracies not included.
2. Resolution: 0.1°C.
3. 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.
4. 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).
5. Temperature Coefficient: ±0.05°C /°C for measure, ±0.05°C /°C (< 18°C or > 28°C) for source.
6. Supports pulsed transmitters and PLCs with pulse times as short as 5 ms. |
