An instrument calibration sheet similar to the example on page 21 includes the
following information:
Model This refers to the Geosense
®
model number.
Serial Number This is a unique sensor identification number that can be found
on the cable just behind the NATM cell body and, for long
cables, at the end of the cable.
Works ID Unique works batch and range code
Cal Date Date the calibration was performed
Baro Barometric Pressure at the time of calibration
Temp
o
C Temperature at which the NATM cell was calibrated
DPI No. Serial number of the Digital Pressure Indicator used in
conjunction with the pressure generator
Readout No. Serial Number of the readout used to display the transducer
output
R/O Cal Date The date on which the Readout was calibrated to a traceable
standard
Applied Pressure Pressure applied to the transducer as part of the calibration
cycle in both psi and kPa
Readings [digit] Readings from the transducer as pressure is applied and as
pressure is reduced, in steps. The average is calculated.
Calculated Pressure Calculation of the applied pressure using the calculated Linear
and Polynomial for comparison with the actual Applied
Pressure.
Non Lin. % FSO Non Linearity expressed as a percentage of the transducers
Full Scale.
Calibration Factors ‘ Linear ’ and ‘ Polynomial ’ factors are provided for a selection of
engineering units ( other units can be calculated directly from
the kPa values ). Examples of calculated values are detailed
on the next page.
