conformance of at least 3
σ
.
Accuracy
Refer to Table 5-1 on page 5-10.
Stability
±0.1% of reading or 0.1 °C, whichever is greater, for 24 months for RTDs
±0.1% of reading or 0.1 °C, whichever is greater, for 12 months for
thermocouples
5 Year Stability
±0.25% of reading or 0.25 °C, whichever is greater, for 5 years for RTDs
±0.5% of reading or 0.5 °C, whichever is greater, for 5 years for
thermocouples
Power Supply Effect
Less than ±0.005% of span per volt
RFI Effect
Worst case RFI effect is equivalent to the transmitter’s nominal
accuracy specification per Table 1 on page 13 when tested in accordance
with ENV 50140, 30 V/m, 80 to 1000 MHz, with unshielded cable.
Vibration Effect
Transmitters tested to the following specifications with no effect on
performance:
Self Calibration
The analog-to-digital measurement circuitry automatically
self-calibrates for each temperature update by comparing the dynamic
measurement to extremely stable and accurate internal reference
elements.
