Calibration Troubleshooting Use calibration history with process records, maintenance events, environmental data, and independent checks when investigating process drift. Contents Can Calibration Data Reveal a Manufacturing Process Problem? Calibration data and process data are different Look for repeated changes Compare dates and equipment records Check the measurement system first Use controlled checks Treat relationships as evidence to investigate Decide what needs correction Investigation checklist Related measurement investigations Can Calibration Data Reveal a Manufacturing Process Problem? Calibration records hold measurement details. Manufacturing records track production activities. When a measurement trend shifts, it’s helpful to review both records. However, it’s crucial to keep their purposes distinct. Calibration data alone doesn’t prove a change in the manufacturing process. It can support the investigation of a possible link.
