28 II Ex Users Manual Temperature Range Resolution Accuracy [1,2] -200 °C to +1090 °C 0.1 °C ±(1.0 % + 10) -328 °F to +1994 °F 0.1 °F ±(1.0 % + 18) [1] Does not include error of the thermocouple probe. [2] Accuracy specification assumes ambient temperature stable to ± 1 °C. For ambient temperature changes of ± 5 °C, rated accuracy applies after 2 hours.
