6.3.1 Data Reduction overview contd...
An instrument calibration sheet similar to the example in the Section 6.6 of this manual in-
cludes 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 load 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 load cell was calibrated
Applied Pressure Pressure applied to the transducer as part of the calibration
cycle
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
3rd order Polynomial for comparison with the actual Applied
Pressure.
Error % FSO Non Linearity expressed as a percentage of the transducers
Full Scale.
Calibration Factors ‘‘ Polynomial ’ factors are provided for conversion to kN
An example of the calculation from Linear Digits ( Hz
2
/1000) to kN using a polynomial equa-
tion is given below:
