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 an instrument is functioning correctly.
- Adjustment: The act of altering a measurement instrument to bring it into alignment with a standard.
- 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 falls outside the specified acceptance criteria.
- Drift: The gradual change in an 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 periodic check performed to ensure that the instrument remains within specified limits between calibrations.

8. Calibration Strategy
Calibration will follow the As Found then As Left logic. The minimum number of points for calibration will be five, including endpoints and midpoints within the specified range of 0 to 5 bar. It is recommended to take three replicate readings at each point to ensure accuracy and reliability.
9. Step-by-Step Procedure
- Preparation: Gather all necessary tools and reference standards.
- Stabilization: Allow the TMP Sensor to stabilize as per manufacturer recommendations.
- As Found checks and data capture: Record initial readings and conditions before any adjustments.
- Adjustment rules: If OOT is detected, follow adjustment protocols if allowed; otherwise, escalate the issue.
- As Left verification: Confirm that the instrument is functioning within specifications after adjustments.
- Labeling + documentation completion: Ensure all calibration records are filled out accurately and contemporaneously (ALCOA+).
10. Acceptance Criteria & Calculations
The acceptance criteria for the Ultrafiltration TMP Sensor is ±1%. The error calculation formula is:
Error (%) = (Observed Value – True Value) / True Value × 100
Pass/Fail logic: If the calculated error falls within the acceptance criteria, the calibration is deemed acceptable. Rounding rule: [TBD].
11. Handling OOT / Failures
- Immediate containment: Tag the equipment and stop 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: 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.
