For accurate full scale measurements below -40 degrees, you may need to
complete the full scale cold junction calibration procedure (Refer to
Section 16.3.1, Special Cold-Junction Calibration).
Calibration: NIST #135, DIN 43710
Reference Junction: Either a remote ice-point cell or an oven can be used in
place of the Cold-Junction Compensation Board. Curvalinear correction to
better than 40 dB ambient temperature rejection.

Cu10(Linear) -200 to 200 : 1.0 -328 to 392 : 2.0
(Either of the two linearizations or the non-linearized scaling may be applied to RTDs
with R-zero values as low as 10 ohms or as high as 1000 ohms, using field
calibration and selection of excitation and input range.)
