justering

Justering is the act of bringing something into alignment or to a desired state by making adjustments. The term, used in Swedish and other Nordic languages, covers changes to position, settings, or parameters to meet a specification or improve function. Etymologically, it derives from the verb justera, meaning to set right or align.

In engineering and manufacturing, justering involves aligning components, setting clearances, and tuning mechanisms so that moving parts fit and operate smoothly. It is distinct from kalibrering, which refers to calibrating instruments to ensure measurement accuracy rather than relative positioning.

In optics and photography, justering refers to aligning lenses, focusing, and adjusting exposure or white balance to achieve the intended image. In electronics, audio, and video, it describes setting gains, thresholds, equalization, or signal routing to optimize performance.

The common workflow includes defining a target or spec, measuring deviation, applying an adjustment, and verifying the result against the target. Documentation or record-keeping is often part of formal justering procedures, especially in manufacturing or safety-critical contexts.

Tools and methods vary by field but can include gauges and dial indicators for mechanical work, alignment jigs, shims, and software-based calibration routines. See also alignment, calibration, and tuning.
