DC Voltage Input: Use scaling resistors to reduce the full scale voltage to 0 to
60mv. SEE SECTION 5.6.3 FOR SCALING RESISTORS VALUES OF RA
AND RB.

Current Transmitter Inputs: Use scaling resistors to convert the current to a
voltage input scaled to 0 to 60mv. This will result in a 0 to 20ma full scale range,
and an Mx + B scaling can be in the computer to display the engineering units.
