Calibration Management
Calibration management software for gauges, instruments and audits
Calibration due dates live in a spreadsheet, certificates in a binder, and nobody can say which parts were measured with the gauge that just failed. Agnotic Technologies builds calibration management software that tracks every gauge, schedules each calibration and traces the impact when one is out of tolerance.

What is calibration management software?
Calibration management software keeps a register of every gauge and instrument a plant uses to accept product, schedules each calibration from its interval, stores the certificate and results, and blocks or flags a gauge that is overdue or out of tolerance. Agnotic Technologies builds it around your own gauge list, intervals and labs, whether calibrations are done in house or by an outside lab. When a gauge fails, the software lists the parts and lots it measured since its last good calibration, so quality can decide what to recheck. Auditors get the full history of any instrument in one place instead of a binder and a spreadsheet.
Audit readiness
How do we track gauge calibration due dates before an ISO 9001 audit?
Put every gauge in one register with an interval and a next due date, and let the software send the due list to the owner and the calibration lab before the date, not after it. A gauge that passes its due date changes status and cannot be picked on an inspection record until it is recalibrated.
Before an audit, the quality lead runs the report an auditor usually asks for: every gauge in use, its last calibration, its certificate and its next due date, with any overdue or missing record flagged so it can be fixed first.
Gauge record
What does each gauge record hold?
One record per instrument, so its whole history answers one search.
Calibration plan
- Interval in days or in uses
- Procedure or work instruction
- Acceptance limits
- In-house or outside lab
Calibration events
- As-found and as-left results
- Pass or fail against the limits
- Certificate file and lab name
- Reference standards used and their traceability
Usage
- Inspection records that used the gauge
- Parts and lots it measured
- Check-out and return to the crib
Out-of-tolerance flow
What happens when a gauge fails calibration?
The impact review the software runs, so a failed gauge never leaves an open question about parts already shipped.
Record the as-found result
The lab or technician enters an as-found value outside the limits, and the gauge moves to out-of-tolerance status.
Find what it measured
The software lists inspection records, parts and lots measured with the gauge since its last passing calibration.
Assess the impact
Quality compares the gauge error with the tolerances on those parts to see whether bad parts could have been accepted.
Recheck, hold or release
Lots at risk are rechecked, held or released, each with a recorded reason and approver.
Open a CAPA when needed
Repeated failures or damage open a corrective action linked to the gauge record.
Return to service
The adjusted and recalibrated gauge returns with its new certificate and next due date.
Gauge status
Which status can a gauge have?
The status rules the inspection screens follow. Each gauge is in exactly one status.
| Code | Name | Typical use |
|---|---|---|
| ACTIVE | In calibration | Can be picked on inspection records |
| DUE | Due soon | Still usable; the owner and the lab are reminded |
| OVERDUE | Past its due date | Blocked from new inspection records until recalibrated |
| OUT | Out for calibration | Off the floor, with the expected return date tracked |
| OOT | Out of tolerance | Blocked, and an impact review is opened |
| RETIRED | Retired or lost | Kept in history and never selectable again |
Audit evidence
What auditors usually ask to see
Answered from the calibration records, not assembled by hand the week before.
- The list of measuring equipment in use and where it is
- The last calibration and certificate for a sampled gauge
- Traceability of the reference standards the lab used
- What was done when a gauge was found out of tolerance
- How overdue gauges are kept out of use
- Who calibrated, checked and released each instrument
What do we build into calibration management software?
Modules for the gauge crib, the lab and the quality office.
Gauge register
Every instrument with its labels, limits, owner, location and status.
Calibration scheduling
Due lists by interval or usage, with reminders to owners and outside labs.
Results and certificates
As-found and as-left values checked against limits, with certificates attached.
Use blocking
Overdue and out-of-tolerance gauges cannot be picked on inspection records.
Certificate reading
AI reads outside lab certificates into result fields for a technician to confirm.
Impact review
Reverse traceability from a failed gauge to the parts and lots it measured.
Check-out and crib
Barcode check-out and return, so the software knows who has each gauge.
Integrations
Inspection systems, CMMS and QMS, so status and usage stay in step.
Failure points
Why do spreadsheets miss calibration dates?
Where calibration tracking breaks before it moves into software, and what changes.
Challenge
The due date is a cell nobody looks at until the audit.
Agnotic approach
Due lists go to owners and labs automatically, and late gauges change status.
Challenge
An overdue gauge is still in the drawer and still used.
Agnotic approach
Overdue gauges are blocked on inspection records, so use stops at the point of measurement.
Challenge
Certificates are in a binder or an email folder.
Agnotic approach
Each certificate is attached to the calibration event it belongs to.
Challenge
Nobody knows what a failed gauge measured.
Agnotic approach
Inspection records store the gauge ID, so the impact list is one query.
Challenge
Personal gauges and spares are never registered.
Agnotic approach
Check-out by barcode puts every gauge in the register before it can be used.

Facts and sources
Which rules require calibration records?
FDA calibration rules and the NIST traceability policy, each linked to its primary source.
For drug makers, 21 CFR 211.160(b)(4) requires instruments, apparatus, gauges and recording devices to be calibrated at suitable intervals under a written program with schedules, accuracy and precision limits and remedial action, and instruments that do not meet specifications must not be used.
Source: 21 CFR 211.160(b)(4) (eCFR)21 CFR 211.68(a) requires automatic, mechanical and electronic equipment used in drug manufacturing to be routinely calibrated, inspected or checked under a written program, and written records of those calibration checks and inspections must be kept.
Source: 21 CFR 211.68(a) (eCFR)Under FDA's good laboratory practice rule, 21 CFR 58.63(c), written records must be kept of all inspection, maintenance, testing, calibrating or standardizing operations, and each record must contain the date of the operation.
Source: 21 CFR 58.63(c) (eCFR)NIST adopts the international vocabulary of metrology definition of metrological traceability: a property of a measurement result whereby it can be related to a reference through a documented unbroken chain of calibrations, each contributing to the measurement uncertainty. NIST also states that other organizations are responsible for establishing the traceability of their own results.

Frequently Asked Questions
Yes, where inspections are recorded in software. Overdue and out-of-tolerance gauges cannot be picked on an inspection record, and a scan of a blocked gauge shows why it is blocked.
Yes. The certificate is the lab's evidence of the result and its traceability. The software attaches it to the calibration event, and AI can read its values into fields for a technician to confirm.
Yes. A gauge can be due after a number of uses, a number of days, or whichever comes first, with the count taken from check-outs or inspection records.
It is the review of everything a gauge measured since its last passing calibration, to decide whether any accepted parts could be wrong. The software builds the list of affected records; quality makes and records the decision.
Yes. Instruments that need repair can open a work order in your CMMS, and the completed work comes back to the gauge record before it returns to service.
We do not publish prices. The number of gauges and sites, labs, use blocking, impact review, integrations and migration decide the size, and we agree a fixed first release on the scoping call.
