Calibration is often treated as a routine requirement - something that needs to be done to satisfy audits or scheme requirements.
But in practice, calibration plays a much bigger role. It underpins the accuracy of testing, the consistency between engineers, and ultimately the confidence you have in the results being recorded.
The real issue
What we often see isn’t a lack of calibration - it’s a lack of control around it.
- meters calibrated but no system
- inconsistent methods
- unclear records
- engineers interpreting results differently
What good looks like:
- defined calibration process
- master reference instruments
- consistent methods across engineers
- clear records and traceability
- planned calibration intervals
Where problems show up:
- safe isolation checks
- commissioning inconsistencies
- audit findings
- conflicting readings between engineers
Calibration isn’t just a technical process, it’s part of competence.
Whether calibration is carried out externally or managed in-house, the key is having a system that is consistent, controlled and understood by the people using it.
We’ve recently added more detail on how we support calibration and in-house calibration training here.
