thinking about possibility of using a thermocouple input of RA22 controller to measure a voltage across a shunt resisitor - to measure the DC current. Haven't found any information if the input must be floating, or can be tied to a potential of DC source.

Hi,
thinking about possibility of using a thermocouple input of RA22 controller to measure a voltage across a shunt resisitor - to measure the DC current. Haven't found any information if the input must be floating, or can be tied to a potential of DC source.
Thanks n regards
