Figures 6, 7, 8, 9, and 10 show the errors for each thermocouple
type when connected to the NI 9213E with the autozero channel
on. The figures display the maximum errors
1
over a full
temperature range and typical errors at room temperature. The
figures account for gain errors, offset errors, differential and
integral nonlinearity, quantization errors, noise errors, 50
Ω
lead
wire resistance, and cold-junction compensation errors. The
figures do not account for the accuracy of the thermocouple itself.

The maximum errors assume an isothermal error of 1.3 °C. Refer to the
Cold-Junction Temperature Measurement Accuracy
section for more information.
