Answer / mohammad asfani
there is one formula with graphitical y=MX+b
for exma:Given a temperature transmitter with a measurement

degrees and a signal range of 4 to 20 milliamps, calculate
the proper signal output at an applied
temperature of +41 degrees.
Ans:take 41 deg and subtract to lrv mens -88. then 129 will
come and then you devide by span rang of transm..likespan
(145--88)=233,129/233=0.55 and take this number and
multiply by spanof current signal like 16ma and addto lrv
after that you can get ans...
