400°C-1370°C	±(0.3% reading + 1°C)
-328°F - -400°F	±(0.5% reading + 2°F)
-200°F - 200°F	±(0.3% reading + 2°F)
200°F - 400°F	±(0.5% reading + 2°F)
400°F - 2498°F	±(0.3% reading + 2°F)

Note:

Temperature Coefficient:

For ambient temperatures from 0°C - 18°C and 28°C - 50°C, for each °C ambient below 18°C or above 28°C add the following tolerance into the accuracy spec.

0.01% of reading + 0.03°C

(0.01% of reading + 0.06°F)

The basic accuracy specification does not include the error of the probe. Please refer to the

probe accuracy specification for additional details.
