NI-9210 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.
Conditions
Specifications are valid for the range -40 °C to 70 °C unless otherwise noted.
Connector Types
The NI-9210 has more than one connector type: NI-9210 with mini-TC and NI-9210 with spring terminal. Unless the connector type is specified, NI-9210 refers to both connector types.

Temperature Measurement Accuracy
|
The following figures show the typical and maximum errors for each thermocouple type when used with the NI-9210 over the full temperature range and autozero on as well as the typical errors at 23 °C, ±5 °C without autozero. 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.
NI-9210 with
Mini-TC Safety Voltages
Connect only voltages that are within the following limits:
|
Measurement Category I
Measurement Category I is for measurements performed on circuits not directly connected to the electrical distribution system referred to as MAINS voltage. MAINS is a hazardous live electrical supply system that powers equipment. This category is for measurements of voltages from specially protected secondary circuits. Such voltage measurements include signal levels, special equipment, limited-energy parts of equipment, circuits powered by regulated low-voltage sources, and electronics.
NI-9210 with
Spring Terminal Safety Voltages
Connect only voltages that are within the following limits:
|
Measurement Category II
Measurement Category II is for measurements performed on circuits directly connected to the electrical distribution system. This category refers to local-level electrical distribution, such as that provided by a standard wall outlet, for example, 115 V for U.S. or 230 V for Europe.

Calibration
Calibration interval | 1 year |
1 Measurement sensitivity represents the smallest change in temperature that a sensor can detect. It is a function of noise. The values assume the full measurement range of the standard thermocouple sensor according to ASTM E230-87.
