SCC-TC Series Thermocouple Input Modules User Guide
Note
The accuracy specification includes the combined effects of the temperature sensor
accuracy and the temperature difference between the temperature sensor and any
thermocouple connector. The temperature sensor accuracy includes component tolerances,
temperature drifts, and self-heating effects. It does not include measurement device errors.
