What is Dimensional Calibration?
Dimensional calibration is the process of verifying and adjusting measuring instruments by comparing them with certified reference standards to ensure accurate measurement results. This process helps identify measurement deviations and ensures instruments operate within specified tolerances.
Dimensional calibration is widely used for instruments that measure:
- Length and distance
- Diameter and thickness
- Flatness and parallelism
- Angles and geometric parameters
Regular calibration helps organizations maintain quality control, regulatory compliance, and product consistency.
