I have a Cylinder head thermocouple which is electrically connect to the head. The electronic circuit that is attached to the AD597 output, has the same ground -ve. I therefore have a ground loop. Any suggestions as to how get the AD597 to read correctly with this configuration ?

 

Thanks Wallace
