PT100 Wiring help

hadtstec

Hi there
I have bought the PT100 Board from E3D-Online as well as their sensor, but I am not getting a reading.
I have updated the Firmware with "M305 P1 X200", but am not seeing anything.

My Question: Is this the right board?

I bought this:

But am wondering if I should have bought this:

Many Thanks

solve this equation and you have your answer:

Thermocouple != PT100

Unfortunately, yes, you should have. Probably cheapter to just buy a K-type thermocouple than another board though, unless you needed both channels?
