9.3. Calibration Validity
Calibration validity remains the responsibility of the user. Individual codes of practice may dictate
calibration intervals.
Regular calibration establishes a pattern of reliability and enables the calibration check period to
be modified in line with operational experience. As a guide, the higher the risk, the more
frequently calibration should be checked.
