Appendix A. 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.
