  • Page 7: High-Vibration Application Connections

    NI-9940 backshell kit to protect connections to the NI-9213. Common-Mode Voltage The NI-9213 common-mode range is the maximum voltage between any channel and COM. If COM is not connected, then the common-mode voltage range is the maximum voltage between any two channels. The NI-9213 measures the common- mode voltage level of each channel and returns a warning in the software if the signal is outside the common-mode voltage range.

  • Page 8: Minimizing Thermal Gradients

    Minimize adjacent heat sources and air flow across the terminals. ■ Keep the ambient temperature as stable as possible. ■ Make sure the NI-9213 terminals are facing forward or upward. ■ Keep the NI-9213 in a stable and consistent orientation. ■...

  • Page 9: Timing Modes

    Autozero Channel The NI-9213 has an internal autozero channel, which can be subtracted from each thermocouple reading to compensate for offset errors. Use of the autozero channel is optional, however the NI-9213 specifications assume that autozero is applied to every sample.
