Elements and Performance Criteria
- Prepare items for calibration
- Select the authorised calibration procedure in accordance with enterprise procedures
- Identify hazards and use appropriate personal protective equipment, 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
- 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) if 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
- Document results
- Document compliance/non-compliance with requirements of test and/or specifications
- Estimate and document uncertainty of measurement in accordance with enterprise procedures, if required
- Record the results of each test/calibration accurately, unambiguously and objectively
- Ensure confidentiality of enterprise information
- 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 enterprise procedures
- Store test equipment/measurement standards and results in accordance with enterprise procedures
