Worked scenario
Base example
Intended test length is 100 mm. All other inputs remain at the base values.
| Input | Value | Unit |
|---|---|---|
| Intended test length | 100 | mm |
| Measured horizontal length | 97 | mm |
| Measured vertical length | 99 | mm |
| Current zoom | 100 | % |
Calculated results
| Result | Value | Unit |
|---|---|---|
| Horizontal corrected zoom | 103.0928 | % |
| Vertical corrected zoom | 101.0101 | % |
| Axis mismatch | 2.0408 | % |
Worked scenario
Smaller first input
Intended test length is 80 mm. All other inputs remain at the base values.
| Input | Value | Unit |
|---|---|---|
| Intended test length | 80 | mm |
| Measured horizontal length | 97 | mm |
| Measured vertical length | 99 | mm |

Square the projection to the work surface first. Apply a scale correction only after both axes measure consistently.
