What action should be taken if a technician realizes they've recorded measurement values incorrectly?

The correct response involves crossing out the incorrect entries and documenting corrections clearly. This method maintains an accurate and verifiable record of the data that was collected. It provides a clear trail of what was originally recorded as well as what the corrected measurements are.

Crossing out the incorrect values and writing the correct ones nearby helps to ensure that there is no confusion about which data is valid. It preserves the integrity of the data record by showing exactly what was initially measured and how it has been amended. This transparency is essential in calibration processes, where traceability and accuracy are crucial for quality assurance.

This approach also upholds any regulatory or organizational standards regarding documentation practices. Maintaining a clear and correct audit trail for all measurements is critical in calibration to avoid future misunderstandings and ensure compliance with quality management systems.

Other actions, such as deleting the incorrect values or simply circling them without proper documentation, do not provide the same level of accountability and clarity. Notifying the quality manager to disregard the sheet altogether can lead to lost data and further issues, which emphasizes the importance of proper documentation and correction methods.
