1. The published digital accuracy applies over the entire sensor input range. Digital output can be accessed by HART Communications or WirelessHART.
2. Total digital accuracy for thermocouple measurement: sum of digital accuracy +0.8 °C (cold junction accuracy).
3. Digital accuracy for NIST Type B T/C is ±4.5 °C (±8.1 °F) from 100 to 300 °C (212 to 572 °F).
4. Digital accuracy for NIST Type K T/C is ±1.05 °C (±1.895 °F) from –180 to –90 °C (–292 to –130 °F).
