Description This item was bought in error and has never been used in anger for any project.  It is perfectly functional and has no damage but there are couple of witness marks where it has been slide in and out of the housing.  There are image in the lot showing the device working by using the NI MAX software and an NI USB-9162.

NI-9211 Specifications

Definitions

Warranted  specifications describe the performance of a model under stated operating conditions and are covered by the model warranty.

Characteristics  describe values that are relevant to the use of the model under stated operating conditions but are not covered by the model warranty.

• Typical  specifications describe the performance met by a majority of models.
• Nominal  specifications describe an attribute that is based on design, conformance testing, or supplemental testing.

Specifications are  Typical  unless otherwise noted.

The following figures show the typical and maximum errors for each thermocouple type when used with the  NI-9211   over the full temperature range and autozero on. The figures account for gain errors, offset errors, differential and integral nonlinearity, quantization errors, noise errors, and isothermal errors. The figures do not account for the accuracy of the thermocouple itself.
