A general calibration reference allows you to use a known dimension in any direction, not only along the X or Y axis.
When to use it
It is useful, for example, when:
- a reliable dimension is angled,
- the source contains known dimensions in different directions,
- you want the calibration to be based on several geometrically diverse references.
Principle
Each active reference is included in the combined calibration calculation. An inactive reference remains stored in the project but is excluded from the calculation.
Diagnostics
JustMeasure compares individual references and warns about inconsistencies between them. A larger deviation does not automatically mean an application error – it may indicate an inaccurate source, an incorrect stated dimension or imprecisely placed points.
