The due-date control loop
- Set the intervalUse the approved procedure, manufacturer guidance, history, and risk to support the interval decision.
- Record the next due dateKeep the date traceable to the last completed calibration and the chosen interval.
- Review upcoming workUse lead times that give the team enough time to schedule internal or outside-provider work.
- Escalate overdue workKeep overdue instruments visible and follow the organization's procedure for the exception.
- Close the loopRecord the calibration result, certificate, and next due date so the cycle starts again.
Use status to prioritize the next action
| Status | Meaning | Next action |
|---|---|---|
| Current | The next due date is more than 30 days away. | Continue normal control. |
| Due soon | The next due date is within 30 days. | Schedule or confirm the work plan. |
| Overdue | The next due date has passed. | Follow the approved overdue procedure and keep the exception visible. |
| Out of service | A failed result or manual decision makes the instrument unavailable. | Prevent use and follow evaluation, repair, recall, or disposition steps. |
Make reminders actionable
- Choose lead times such as 30, 14, 7, and 1 day when the work requires planning.
- Send summaries on weekdays when the team can act.
- Include workspace members, instrument assignees, or additional recipients who own the response.
- Keep overdue work in the summary until the record is updated.
- Review recipients and ownership when people or responsibilities change.
A weekly calibration review checklist
Choose a regular review time and an owner who can coordinate with production and calibration providers. Start with the current register and last week's open actions. Use the checklist below in your team's meeting notes; the review frequency and escalation rules should follow your own procedure.
| Review | Question to resolve | Record before closing |
|---|---|---|
| Overdue instruments | Which dates have passed, and who needs to act? | Instrument ID, responsible person, action and follow-up date. |
| Out-of-service instruments | Is the instrument's unavailability clear to the people who might use it? | Current status and the reference to the evaluation or disposition record. |
| Upcoming work | Does the provider's turnaround time fit the production schedule? | Booking or internal work plan and an owner. |
| Completed calibrations | Are the result, performed date and next due date recorded? | The calibration record and any missing information to obtain. |
| Certificates | Can the evidence be retrieved from the correct instrument and event? | Certificate reference or an action to obtain the missing file. |
| People and locations | Have instruments moved or responsibilities changed? | Updated location, owner and reminder recipients. |
| Open actions | What remains unresolved from the previous review? | The next step, one accountable owner and the next review date. |
Worked example: plan around provider turnaround
Suppose an outside calibration provider needs 10 business days and a pressure gage is due September 30, 2026. In a September 14 review, the owner should confirm shipping time, provider availability, and whether production needs a replacement instrument. A reminder arriving only one day before the due date would leave little time to arrange that work.
Record an action such as: PG-014; owner: Quality; next step: confirm provider booking and production coverage; follow-up: September 15. This example is a planning exercise, not a recommended calibration interval or permission to use an overdue instrument. Keep the approved due date until an authorized decision changes it.

The calibration due date says when the instrument's calibration is due. An action follow-up date says when a person should report back about a booking, missing certificate, or other task. Moving the calibration date to match an unfinished action hides the original exception.
Keep the action owner, next step, follow-up date and evidence reference in your team's action log. Update the instrument record when the calibration is completed or an authorized decision is documented. GagePilot's instrument queue and reminders support the review; this checklist does not imply a separate task-management feature.
The date is a control point, not the whole decision
A date can tell the team that a review is due. It cannot determine whether an extension, risk assessment, interval change, repair, or recall is acceptable. Document those decisions through the approved quality procedure and keep the register aligned with the result.
GagePilot connects the due date to status, reminders, records, and evidence so the team has a clear place to act.
