The calibration involves the following steps:
- Minimum thermal conditioning of 4 hours at controlled temperature and humidity.
- Functional verification and verification of the pre-calibration reading of the instrument with comparison samples.
- Possible adjustment of the instrument
- DIMENSIONAL CALIBRATION OF THE INDENTOR AND THE ANULAR FOOT
- CALIBRATION OF FORCES APPLIED BY THE INDENTOR AND BY THE ANULAR FOOT
- CALIBRATION OF THE DISPLACEMENT OF THE INDENTOR
- CALIBRATION OF THE TIME OF DURATION OF THE TEST
- Verification of the post-calibration reading of the instrument with comparison samples.
- Preparation of the Accredia Calibration Certificate which shows all the measures described above.
At the end, the instrument is packed for the shipment.

What happens if the instrument does not measure correctly ? 
- If during calibration, all the characteristics of the instrument are compliant with the provisions of the reference standard, the Declaration of Conformity of the instrument that certifies full compliance for use is shown in the Calibration Certificate.
