During what process is the calibration of instruments typically checked?

The calibration of instruments is typically checked during a quality audit. Quality audits are formal evaluations of an organization's processes, systems, and outputs to ensure compliance with internal standards as well as external regulations. During these audits, one key aspect examined is the accuracy and reliability of measuring and testing equipment. Proper calibration is critical to ensure that instruments produce valid and consistent results, which is essential for maintaining quality standards in production and service delivery.

In the context of a quality audit, the auditor will review the calibration records, procedures, and the condition of the instruments themselves. This ensures that all measurement tools are functioning within the specified tolerances, supporting the overall effectiveness of the quality management system.
