Fisher Number Map Report
To run the Fisher Number Map Report, scroll to the bottom of the Records window and tap Fisher Number Map.
A Fisher number map is a polynomial that relates SAS particle size to Fisher number for a particular material. The Fisher particle size shown in reports is the Fisher number displayed with units of μm.
| Field or Button | Description |
|---|---|
| Cancel [button] | Discards any changes. |
| Coefficients | The coefficients used in the equation. |
| Degree [button] | The coefficients give the nth order term from a polynomial fit. Coefficients higher than the degree of the polynomial are not displayed. Zero is shown for coefficients that are not determined because of an insufficient number of included points. R2 is the usual R-squared statistic. |
| Fisher Number [column] | The Fisher number from an analysis run on an instrument that uses Fisher number. |
| Include [check box] |
Select to include in the fit. Errors are indicated for SAS particle sizes in enabled rows that are not greater than zero and strictly increasing. The graph is not updated, and Save is disabled when any fields have errors. Selecting a row or focusing the Fisher number field highlights the corresponding point in the graph. Changing the selections or the Fisher number for a selected point updates the coefficients, R2, and the graph. |
| Include origin [check box] | If selected, a point at 0, 0 is included in the line fit. |
| Material [drop‑down box] | Comes from the SOPs, records, and other maps. This map will be used to determine the Fisher number for all records with the selected material. |
| SAS Particle Size (μm) [column] |
Enter the particle size from the analysis run on the MIC SAS II. |
| Save [button] | Saves changes. |

x-axis |
The x-axis is SAS Particle Size (μm) and the y-axis is Fisher Number. The lower axis limits are zero; the upper limits are autoscaled. The fit is shown as a smooth curve without points in orange. A legend identifies the two data sets. |
