*Note: Total system accuracy in the chamber includes thermocouple wire accuracy.
Thermocouple wire accuracy is ±1°C or 0.75% of reading, whichever is greater. Therefore, total
system accuracy over the chamber’s operating range can be as much as ±2.66°C, although the
typical accuracy is often better than ±1.0°C.
