*Includes reference junction calibration of ± 0.01 degrees using the standard "ice bath" method of calibration. Factory accuracy at
reference ± 1.2 °F. Note that factory accuracy may have typical variations of ± 150 microvolts or ± 0.6 ohms for RTDs which
means field calibration may be required to achieve stated accuracy.
