Elements and Performance Criteria

1. Prepare items for calibration
   • Select the authorised calibration procedure in accordance with workplace procedures
   • Identify hazards and use appropriate personal protective equipment (PPE), safety equipment and procedures
   • Confirm all measuring equipment meets the laboratory's specification requirements and complies fully with the calibration procedure
   • Assemble and set up specified reference standards and associated equipment prior to testing
   • Verify performance of reference standards and measuring equipment prior to use and adjust or calibrate as necessary
   • Identify and minimise potential sources of measurement error
2. Perform calibration
   • Perform individual tests without variance according to the documented procedure to ensure repeatability of measurement
   • Confirm readings are the result of a valid measurement and record data as required (as-found or before adjustment)
   • Adjust device under test to bring readings within specification and record data (as-left or after adjustment) where required
   • Analyse resulting test data to detect trends or inconsistencies that would significantly affect the accuracy or validity of test results
   • Seek appropriate advice when interpretation of results is outside authorised scope of approval
3. Document results
   • Estimate and document uncertainty of measurement in accordance with workplace procedures, where required
   • Document compliance/non-compliance with test requirements and/or specifications
   • Record the results of each test/calibration accurately, unambiguously and objectively
   • Ensure confidentiality of workplace information
4. Finalise calibration
   • Prepare and issue a final report on the job/item detailing testing carried out, traceability, statement of compliance and relevant information as required
   • Report any non-compliance and verify next course of action with supervisor
   • Attach calibration labels, equipment stickers, quality control tags and tamper resistant seals as required in workplace procedures
   • Store test equipment/measurement standards and results in accordance with workplace procedures
