In the procedure no.9, if the process controller has analog input range 2-8 Vdc to represent the temperature range 0-100 degree Celsius, we have to modify our circuit for archive the new range and renew the parameter of transmitter. Firstly, we know the range of our circuit is 1-5 Vdc. Then, in our circuit has only 250 ohms resistor so if we series two 250-ohm resistor, we get the new range 2-10 Vdc. (From V = IR; Standard signal 4-20 mA so 2 V = 4 mA*500 and 10 V = 20 mA* 500 ) The parameter that we have to setup in computer is range follow to the new range 2 -10 Vdc and the temperature is follow to this calculation below.
