Measurement accuracy inevitably changes over time.
Environmental exposure, ageing, contamination and normal component wear may gradually influence sensor performance.
For this reason, calibration should be regarded as a continuous engineering process rather than a one-time installation activity.
The platform should maintain records including:
- calibration dates
- calibration procedures
- calibration coefficients
- responsible operator
- verification results
Maintaining complete calibration history improves engineering traceability while increasing confidence in analytical conclusions.
