A calibration register for tracking measuring and monitoring equipment: equipment ID and description, calibration standard and traceability, interval, last and next due date, as-found/as-left results, and the out-of-tolerance (OOT) handling procedure. Built to support ISO 9001, AS9100, IATF 16949, and ISO 17025-traceable calibration programs. Generated instantly, no login required.
Calibration Note: If a gauge is found out of tolerance, the impact isn't limited to that calibration event — you must assess every measurement taken with that gauge since its last known-good calibration and determine whether affected product needs to be re-verified.
Equipment Register
Equipment ID, description, manufacturer/model, serial number, location, and owner/department
Calibration Schedule
Interval, last calibration date, next due date, and calibration method/standard used
As-Found / As-Left Results
Table logging each calibration event with as-found reading, as-left reading, pass/fail, and technician
Out-of-Tolerance Handling
OOT investigation fields: affected date range, product impact assessment, disposition, and corrective action
What equipment needs to be on a calibration log?
Any measuring and test equipment (M&TE) used to accept or reject product, or to verify that a process is in control — calipers, micrometers, torque wrenches, gauges, scales, thermocouples, and similar instruments. Equipment used only for reference, not acceptance decisions, is typically excluded.
How do I set a calibration interval?
Start with the manufacturer's recommended interval, then adjust based on usage frequency, environment, and observed drift history. Equipment that repeatedly comes back in tolerance can often move to a longer interval; equipment that drifts should be shortened.
What is 'as-found' vs 'as-left'?
As-found is the reading measured before any adjustment is made during calibration — it tells you whether the equipment was accurate throughout its use since the last calibration. As-left is the reading after adjustment, confirming the equipment leaves calibration within tolerance.
What do I do if a gauge is found out of tolerance?
Open an out-of-tolerance (OOT) investigation. Identify every measurement or acceptance decision made with that gauge since its last known-good calibration, assess whether affected product is still conforming, and disposition accordingly — this is required under ISO 9001, AS9100, and IATF 16949.
