Hi Dear.
As you mentioned here taht transmitter's out put 0% and 100% (SPAN) is ok, but inbetween outputs having errror. So you are facing withe " LINEARITY PROBLEM "means out put is not linear , and that always should be linear. so go to linearity section by HART communicator ,hopefully I have answered your question.Regards
