Hello,
I am working with the ADS1248 for data acquisition from a thermocouple. I am willing to make the cold junction compensation with a three wires PT100 as suggested in the example for temperature measurement application note.
I wanted to ask about the Isothermal block. Can I buy it or should I build it. I looked but I couldn't find anything for sale. If I should build it is there suggestions about the material or any other recommandation. I will appreciate any information you can provide.
