3.2: Setting Up the Void Percentage Relationship
Once a project is created, the Mix Calibration button appears when the project
settings screen is accessed.
1
Pressing the Mix Calibration button opens up a screen that shows the two calibration values “A” and
“B” that are used in the equation to calculate void percentage from dielectric. The details of the
equation are in Appendix B.
2
Enter previously calculated “A” and “B” values and the equation type used to calculate these values
or press the button to calculate the “A” and “B” values from dielectrics and void
percentage (or percent compaction or density) obtained from cores.
Core Measurement Type:
The core physical property that is to be correlated to dielectrics.
Different options include: Percent Compaction, Percent Voids, and Density.
A Value:
This is the first value used in the equation relating dielectric to another physical property (see
Appendix B for details)
B Value:
This is the second value used in the equation relating dielectric to another physical property (see
appendix B for details)
R-Squared Fit:
This is for information purposes-only and is auto-generated when is selected.
It provides a good indication of confidence level that the calculated equation is useful. Values less than
0.6 – 0.7 lead to low confidence levels.
Core Calibration Equation:
There are two types of core calibration equations: Exponential and Straight
Line. The type entered must match the type used to calculate the A and B values.
