3. Definitions
- Calibration: The process of determining the accuracy of a measurement instrument by comparing it against a standard.
- Verification: Confirmation that a measurement instrument meets specified requirements.
- Adjustment: The process of modifying a measurement instrument to bring it into compliance with specifications.
- As Found: The condition of the instrument prior to any adjustments.
- As Left: The condition of the instrument after adjustments have been made.
- OOT (Out of Tolerance): A condition where the measurement falls outside the specified acceptance criteria.
- Drift: The gradual change in the measurement output of an instrument 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 that characterizes the range of values within which the true value is asserted to lie.
- Intermediate Check: A verification process conducted between calibrations to ensure continued accuracy.

8. Calibration Strategy
The calibration will follow the As Found and As Left logic:
- Minimum number of points: At least 5 points including endpoints (0 and 5000 sccm) and midpoints.
- Replicate readings: Perform 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 Mass Flow Controller to stabilize before taking measurements.
- As Found checks and data capture: Record initial readings and document all observations contemporaneously (ALCOA+).
- Adjustment rules: If OOT is detected, follow the adjustment protocol; if not allowed, escalate to QA.
- As Left verification: After adjustments, verify and document the final readings.
- Labeling + documentation completion: Complete all required documentation and label the equipment accordingly.
10. Acceptance Criteria & Calculations
Acceptance criteria: ±1%
Error calculation formula: Error (%) = (Measured Value – True Value) / True Value × 100
Pass/Fail logic: If the error falls within the acceptance criteria, the calibration passes; otherwise, it fails.
Rounding rule: [TBD]
11. Handling OOT / Failures
- Immediate containment: Tag the equipment and cease its use.
- Notification & deviation initiation: Notify relevant personnel and initiate a deviation report.
- Impact assessment trigger: Define the impact window and review affected results/batches.
- Recalibration after repair/adjustment: Schedule recalibration following any adjustments.
- QA disposition: [TBD]
12. Records & Retention
- Logbook entries: Document all calibration activities in the logbook.
- Calibration report/certificate filing: Maintain records of calibration reports and certificates.
- e-Records: [TBD]
- Label content requirements: Include calibrated date, due date, technician name, and status.
