Thermocouple measurement specifications include cold-junction compensation error (with sensor between 15° and 35° C),
isothermal accuracy and system noise. The specifications assume that the 0.625 V range is used and that ground-referencing
and open-thermocouple detection are enabled for a floating thermocouple. Specifications improve with ground-referencing
enabled and open-thermocouple detection disabled for a floating thermocouple. The specifications also assume that the
cold-junction sensor is between 15° and 35° C.

This appendix lists the specifications of the NI 4350. These
specifications are for 15° to 35° C ambient temperature range for one
year unless otherwise specified. All specifications are relative to
calibration standards and require a 30 minute warm-up period.
Specifications do not include transducer error. Temperature coefficient
is applicable for 0° to 15° and 35° to 55° C. For thermocouples, add the
accessory error in ° C only if the accessory (TC-2190, PSH32-TC6,
CB-27T, TBX-68T) is in the 0° to 15° and 35° to 55° C temperature
range.
