I am using an AD595 with two relays switching between two thermocouples type K. The thermocouple 30cm have a reading on the thermocouple 60m reading is different and is oscillating. Does anyone know how can I fix it?
What thermocouple are you using exactly? Can you also share your schematics for us to check the connections? And also it would be very helpful if you share the scope shots of the output oscillations that you are seeing.
Thanks and Regards,
excuse me for the delay .
I was having some progress and had no definitive circuit to post, since he was changing constantly trying to find one that worked, I chose to continue the development and check for errors.
I am using Thermocouple type K.
Finally the circuit work.
I appreciate your willingness to help.
Thanks and Regards.
