Campbell Scientific CS451/CS456 Pressure Transducer - Manual (Page 37)

Appendix C. Calibration Certificate
Each CS451/CS456 has been calibrated to meet printed accuracy specification
at multiple temperature and pressure ranges. If additional verification is
required, a Calibration Certificate can be purchased for each CS451/CS456
Submersible Pressure Transducer.
The Instrument Data Report provides a list of the pressure and temperature at
which the sensor was tested.
Pressure [kPa] is the pressure applied (listed in kilopascals) to the sensor.
Temperature [°C] is the temperature inside the test chamber at the time of
testing. Pressure After [kPa] represents the resulting measurement output by
the CS451/CS456 at the give pressure and temperature. Finally, Deviation
After [%F.S.], provides the difference between the actual pressure applied to
the sensor and the pressure measurement output by the sensor. This value is
listed as a percentage of the Full Scale range of the sensor.
When a CS451/CS456 is returned to Campbell Scientific for calibration, the
sensor will be returned with an Instrument Data Report. This report will
include values in the Pressure Before [kPa] column. These values represent the
measured pressure the sensor returns at the specified pressure and temperature,
BEFORE calibration.
