with an oper. checking the scale weight calibration, they realize there's no space on the sheet to document the check. They perform the scale weight check anyway. Is this a data integrity error? If s

Yes, this is a data integrity error. The main error would be with the aspect of "Original." While the operator is capturing the original data, they are not recording it in the official, designated record but on their hand. It's important for the original data to be readily accessible, retrievable, and in a durable medium for any future checks or evaluations. In this scenario, recording it on their hand does not fulfill these requirements. Additionally, it might also violate the "Accurate" principle. When the operator transcribes the data from their hand to the official records later, there might be a risk of misinterpretation or transcription errors. To rectify this situation, the operator can ask for additional sheets or a new form where he can record the data right away after performing the check to ensure data integrity.

Yes, this is a data integrity error. It is an original and accurate data integrity error because the operator is not recording the calibration check values contemporaneously with the check being performed.
