First i have to know the connected element
1. RTD :using resistance box and divide the range into 4 quarters for example the range 0 to 100 deg we have 0,25,50,75,100 will find the related resistance from the table and see the transmitter output and if any deviation will make trim zero and span trim.
2. TC the same idea but we use MV supply and by using TC tables.
