Hi,

Is there a way to tell if a probe is connected to the thermocouple amplifier board?

Thank you!

Maybe use this continuity test on a multimeter?

The MCP9600 data sheet describes how three additional high value resistors can be added to implement an open circuit fault flag.

See section 6.3.3.1 “Open-Circuit Detection Technique”

Excellent, thank you!
