Problem with Analog input

Hello M.Fernandes;

I guess we would need more information on the type (make/model)and settings of the 4-20 mA transmitters you are using with the RTDs in your project.

For example, if they are 0-20 mA transmitters and you are reading 4-20 mA, you coiuld have erroneous inputs of the type you show.

We can have better guesses qith better information.

Hope this helps,

Daniel Chartier
