Temperature accuracy

The following graphs show the errors for each thermocouple type when connected to the USB-2001-TC. The

graphs display the maximum errors at 25 °C and over the full operating temperature range, and account for

cold-junction compensation errors. The graphs were generated using thermocouples connected to subminiature

connectors of the same type.

The CJC sensor resolution is 0.0625 °C. This is the minimum value of the CJC step width. As such, the reading

may result in a saw tooth curve rather than a square curve as the temperature inside the board changes. This is

the expected behavior.
