Answer / rijesh

i hope that your calibration liquid you using is water[sg=1]. and your service sg=0.955.if so it is give you the output as per your observation
please make your calibration sg and service sg same value.
if you using service sg =0.95 and you using water for a measurement your maximuma span will be 95% and accordingly step change will effect.

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
