Calibration Reference Guide
Find the governed status record for a measurement instrument.
Start with the instrument’s asset or serial identifier and the plant or area where it is used. Use those details to locate the applicable governed equipment record; do not infer status from a label, nickname, or this guide.
The examples on this page use a fictional manufacturer, Northstar Components. This is a navigation reference, not a live status system, calibration schedule, or work queue. Local Manufacturing Operations and Quality owners maintain the applicable source and support route.
Identify the instrument
Record the identifier exactly as it appears on the instrument or its attached asset label. Include the plant and production area, and distinguish an asset ID from a manufacturer’s serial number. A nickname such as “line gauge” may help a colleague recognize the instrument, but it is not enough to match a governed record.
If the label is damaged or more than one identifier is visible, preserve the details you can read and ask the local quality or equipment-record owner to confirm the match. Do not choose a record based only on similar wording.
Illustrative equipment reference
Fictional Northstar Components examples. These rows show what to identify and where ownership is assigned; they do not state current status or policy.
| Example instrument | Details to collect | Authoritative record owner or source |
|---|---|---|
| Bench micrometer, asset NC-4172 | Asset ID, plant, inspection bench | Plant equipment record; local Quality owns record matching |
| Digital pressure gauge, asset NC-8831 | Asset ID, plant, production line | Plant equipment record; Manufacturing Operations maintains the local source route |
| Supplier-owned reference gauge, serial SG-2048 | Manufacturer serial, supplier, receiving plant or area | Supplier record route coordinated by the local Quality owner |
Worked example: two similar gauge IDs
An operator at fictional Northstar Components’ East Plant sees two nearby labels: “NC-8831” and “NC-8837.” Both appear to refer to digital pressure gauges used on Line 4. The operator notes the exact label, East Plant, Line 4, and the instrument’s location, then asks the local Quality or equipment-record owner to confirm the matching governed record.
The operator does not decide that one record applies because the IDs are close, and does not treat a copied spreadsheet or an older label as proof of current status. The owner confirms which record is relevant through the plant’s approved source and explains the next handoff if the match remains uncertain.
When the record or route is unclear
Use the local Quality or equipment-record owner for the handoff; this guide does not determine instrument status.
The identifier is unreadable. What details should I provide?
Share the plant and area, the instrument type, any readable portion of the asset label or serial number, and where the instrument is located. Ask the local Quality or equipment-record owner to help identify the correct governed record.
I cannot match the instrument to a record. Should I use the closest match?
No. Do not infer a match from a similar ID, nickname, or equipment description. Give the local Quality or equipment-record owner the exact details you can observe and ask them to confirm the record.
Two sources show different information. Which one should I rely on?
Do not resolve the discrepancy by choosing the newer-looking or more convenient copy. Share both source references and the instrument’s identifying details with the local owner responsible for the governed equipment record, and follow their direction.
Who is the service contact?
The local Quality or equipment-record owner identifies the applicable service contact for the plant and equipment type. If that route is not known, ask the local Manufacturing Operations and Quality function to direct you; this page does not provide a universal contact or imply that one route applies at every site.
