The DCS range uses engineering units

Can the DCS range be set from -10 KPA to 10 KPA, with the set point at 0?

The settings in the DCS must be consistent with those of the transmitter unit; if the input pressure of the transmitter is -10kPa to 10kPa, then the settings in the DCS should also be -10kPa to 10kPa.

It is not uncommon for the range to not be 0; all DCS systems support this. Additionally, DCS systems are generally designed to be comprehensive in their functionality – for example, it is possible to set them to operate in reverse mode, such that 4-20mA corresponds to pressures ranging from +10Pa to -10kPa
