I HAVE GOT TYPICAL PROBLEM WITH THE TEMP.INDICATION. THE PROBLEM IS THE K-TYPE T/COUPLE OUT PUT IS CONNECTED TO A INDICATOR.THE INDICATION FLUCTUATES SOME TIMES AND SOME TIME IT IS STABLE. WHEN I CHECKED OUT PUT OF T/COUPLE THE MV WILL NOT VARY. WHERE AS INDICATION FLUCTUATES. WHEN I GIVE MV SOURCE TO T/COUPLE EXTENSIONCABLE FROM THE FIELD IT INDICATION IS STABLE. WHEN GIVE MV SORCE TO INDICATOR ITS INDICATION IS STABLE. PLEASE CLARIFY.
