I am interested how is fifth thermocouple conected from isothermal block to AD8495 on evaluation board CN-0354.
It should be a very short Type K thermocouple wire connected to the REF terminals, and the TC junction mounted close to the AD8495. I will check the assembly instructions and get back to you with details.
I have moved this thread to the Reference Circuits community. Someone here should be able to help you.
We do not ship the fifth "reference" thermocouple with the board.
If a reference thermocouple is not connected, a jumper wire should be connected between terminal 5 and 6 of the screw terminal strip P2.
There will be minimal error because P2 is very close to the AD8495.
Thanks for your question.
