SHUNT CALIBRATION: (Not available on all Transducers)

To Enable the Shunt Calibration – Short together the SHUNT CAL 1 and SHUNT CAL 2 Terminals or wires.

CALIBRATION:

Using the data from the CERTIFICATION OF CALIBRATION:

Full scale OUTPUT = CALIBRATION FACTOR + ZERO OUTPUT

OUTPUT with shunt cal applied = SHUNT CAL OUTPUT + ZERO OUTPUT

ZERO OUTPUT = OUTPUT with zero pressure or load applied.

GROUNDING:

System is usually tied to Earth ground at the Power Supply Return.
