AB Micro 800 analog

I am using an AB Micro 850 with a 2085-IF4 analog input module. How/where do I scale this unit: i.e. engineering units to actual...flow/level/ pH etc.

I want to do this in both ladder logic and function block logic

If you are using CCW as you software platform, then use an "Any to Real" function with one of your analog inputs and then use the "scaler" function and set the output to what ever you need it to be, current, tank level in ft, inches, barrels, gallons, etc.
