Accuracy includes repeatability, hysteresis, load and ambient temperature.
TRANSMITTER REPEATABILITY:
One half of accuracy.
REFERENCE CONDITION ACCURACY:
Equal to transmitter repeatability, when set-up under reference conditions to an external source. The
transmitter is then referenced to the prevailing conditions and transmitter accuracy at this reference
condition will include repeatability, linearity, and hysteresis effects. If using a thermocouple add
0.05
°
F for reference condition accuracy cold junction effect. Reference condition accuracy is
comparable in scope to the accuracy generally specified for analog based transmitters and is
consistent with the ANSI/ISAS51.1-1979 definition of “Accuracy”.
