^{24}It is important to note that you must correctly calculate the corresponding XD_Scale and OUT_Scale
parameter values in order for this to work. The Fieldbus instrument does not calculate the parameters for you,
because it does not “know” how many PSI correspond to how many feet of liquid level in the tank. These
values must be calculated by some knowledgeable human technician or engineer and then entered into the
instrument’s AI block, after which the instrument will execute the specified scaling as a purely mathematical
function.
