0000237: Evaluate 1734 Point IO Thermocouple module and thermocouple for EMI
The Point IO thermocouple module has been installed and a thermocouple has been connected. The module has been configured and is actively reading the thermocouple voltage at a rate of 4 Hz. The system needs to be evaluated for EMI per Fernando's requirements.

I will talk to Fernando about whether he can measure if it puts out any significant noise.

Fernando says he has no way currently to measure radiated noise, but he is not concerned with this system because thermocouple voltage measurement circuits usually do not generate much noise. If in practice they do generate noise he knows of low-noise readout systems we could use instead.
