Definition and context
Calibration establishes how instrument readings relate to reference values and uncertainty. It is distinct from adjustment or verification. A current calibration label alone does not prove a measurement method is suitable for its intended use.
Why calibration matters
Measurement error directly impacts pass/fail outcomes, process capability, and customer confidence.
A robust program defines intervals, tolerances, traceability standards, and escalation rules for out-of-spec instruments.
Program structure
Best practice includes asset registers, due-date alerts, certified references, and clear handling of expired equipment.
When a tool is found out of tolerance, teams should assess the validity of recent inspection results and trigger corrective action.
Where this term fits in the workflow
Calibration is usually shown in the inspection and sampling.
Terms used when teams decide what to inspect, how much to sample, and whether a lot can ship.
What is KaizenQ?
KaizenQ helps factory teams record inspection results, defect photos, and notes in one report shared with the office.

Key takeaways
- Use the calibration range and uncertainty to assess suitability for the measurement.
- Assess affected inspection results when an instrument is found out of tolerance.
