Part Number: CAL-9214

The National Instruments CAL-9214 is a specialized calibration terminal block designed explicitly for use with the high-precision NI 9214 thermocouple input module. This terminal block enhances calibration accuracy by providing solid connections for up to 16 thermocouple channels and 3 cold-junction compensation channels, ensuring reliable temperature measurements. The CAL-9214 connects directly to the front connector of the NI 9214 and features dual jackscrews for secure mounting, which guarantees stability and minimizes the risk of interference or signal loss.

Its pinout configuration facilitates precision calibration and testing, enabling connections to high-accuracy voltage and resistance calibrators. During calibration, users can make necessary adjustments to the voltage and cold-junction compensation channels on the NI 9214 to meet stringent accuracy standards under specific environmental conditions. The CAL-9214 also supports the updating of the EEPROM within the module, storing calibration coefficients and settings to maintain consistent performance.

To achieve optimal results, the CAL-9214 requires an ambient temperature of 23°C ±5°C and the use of shielded copper wire to mitigate noise and thermal offsets. It is critical to adhere to the specified voltage limit of 10 VDC to ensure both safety and functionality. Overall, the CAL-9214 is a robust solution compatible with high-precision calibration systems, such as the Fluke 5520A, making it an excellent choice for various demanding industrial and laboratory applications.
