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.
