3. Definitions
- Calibration: The process of configuring an instrument to provide a result for a sample within an acceptable range.
- Verification: The process of confirming that the instrument meets specified requirements.
- Adjustment: The process of modifying the instrument to bring it within specified limits.
- As Found: The condition of the instrument prior to any adjustments being made.
- As Left: The condition of the instrument after adjustments have been made.
- OOT (Out of Tolerance): A condition where the measurement exceeds the defined acceptance criteria.
- Drift: The gradual change in the instrument’s output over time.
- Traceability: The ability to verify the history, location, or application of an item by means of documented recorded identification.
- Measurement Uncertainty: A parameter associated with the result of a measurement that characterizes the dispersion of the values that could reasonably be attributed to the measurement.
- Intermediate Check: A check performed between calibrations to ensure continued accuracy of the instrument.

- Certificate Validity Check: Ensure calibration certificates are current.
- Standard ID: [TBD]
8. Calibration Strategy
The calibration will follow the As Found and As Left logic:
- Minimum number of points: At least 5 points including endpoints (-20°C, 0°C, 250°C, 500°C).
- Replicate readings: 3 repeats at each point as a best practice.
9. Step-by-Step Procedure
- Preparation: Gather all necessary tools and reference standards.
- Stabilization: Allow the IR Thermometer to stabilize in the calibration environment.
- As Found checks and data capture: Record initial temperature readings at specified points.
- Adjustment rules: If OOT is found, follow escalation procedures; adjustments are only permitted if within scope.
- As Left verification: Confirm that the instrument is within acceptance criteria after adjustments.
- Labeling + documentation completion: Complete all required documentation and label the instrument with calibration details.
Record raw observations contemporaneously to ensure data integrity (ALCOA+).
10. Acceptance Criteria & Calculations
The acceptance criteria for the IR Thermometer is ±2°C. The error calculation formula is:
Error = Observed Value – True Value
Pass/Fail Logic: If the absolute value of the error is within ±2°C, the calibration passes; otherwise, it fails.
Rounding rule: [TBD]
11. Handling OOT / Failures
- Immediate containment: Tag the equipment and stop use.
- Notification & deviation initiation: Notify relevant personnel of the OOT condition.
- Impact assessment trigger: Define impact window and review of affected results/batches.
- Recalibration after repair/adjustment: Ensure recalibration is performed post-adjustment.
- QA disposition placeholders: [TBD]
12. Records & Retention
- Logbook entries: Document all calibration activities.
- Calibration report/certificate filing: Maintain records in accordance with company policy.
- e-Records if applicable: [TBD]
- Label content requirements: Include calibrated date, due date, technician name, and status.
