Campbell Scientific CS450/CS455 Pressure Transducer - Manual (Page 29)

Appendix A. Calibration Certificate
Each CS450/CS455 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 CS450/CS455
Submersible Pressure Transducer.
This document included both the Certificate of Calibration and Instrument Data
Report. A sample for illustration is provided (FIGURE A-1).
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 CS450/CS455 at the given 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 CS450/CS455 is returned to CSI 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.
