No due date can be worked out: no interval or no last calibration recorded
Without a last calibration date and an interval the register cannot show when the instrument is due back, and so cannot show that it is in date. AS9100D asks for the method and frequency in the register itself; ISO/IEC 17025 asks for the next due date in the equipment record.
When the finder raises it
Fires for an instrument in service with no last calibration date or no interval the finder can read. "Before each use" is an interval with no due date and does not fire. Where the register has its own due date, it is used for the schedule and the finding still names the missing column.
A question for the calibration lead
What is the interval, and when was it last done?

ISO 9001 7.1.5Monitoring and measuring resourcesWhere monitoring or measurement is used to check that products and services conform, the organization identifies and provides the resources needed for results to be valid and reliable. It makes sure those resources suit the kind of monitoring and measurement done and are maintained so they stay fit for purpose, and it retains documented information as evidence that they are. Where traceability of measurement is required, or the organization judges it essential to confidence in the results, measuring equipment is: calibrated or verified, or both, at set intervals or before use, against standards traceable to international or national ones (and where none exist, the basis used is recorded); identified so its status is known; and protected from adjustment, damage or deterioration that would make its calibration status or later results invalid. If equipment proves unfit for its purpose, the organization judges whether earlier results remain valid and acts as needed.
Two questions on the row, never counted as findings
- Check, not calibration. Where the control type column says the only date is a verification, an intermediate check, a qualification or a mapping, on an instrument used for product acceptance: the register records a check, not a calibration; confirm the calibration date.
- No rationale. An instrument whose status reads calibration not required, with no rationale recorded: what is the basis, and who agreed it.
