Calibration SOP
1. Purpose
The calibration of the Temperature Data Logger (Single-use mapping) is performed to ensure accurate temperature measurements during temperature mapping processes. This calibration controls risks related to accuracy, patient safety, batch quality, and data integrity, thereby ensuring compliance with regulatory requirements and maintaining the integrity of the cold chain.

- Department/Area: Validation
- Process Use: Temperature mapping
- Parameter: Temperature
- Range: -40°C to 60°C
- Units: °C
- Calibration Frequency: 365 days
3. Definitions
- Calibration: The process of comparing a measurement instrument against a known standard to determine its accuracy.
- Verification: The process of confirming that a measurement instrument meets specified requirements.
- Adjustment: The process of modifying a measurement instrument to bring it into compliance with specified standards.
- As Found: The condition of the equipment prior to any adjustments made during calibration.
- As Left: The condition of the equipment after calibration and any 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 accuracy of a measurement instrument over time.
- Traceability: The ability to trace the history, application, or location of an item through documented recorded identification.
- Measurement Uncertainty: A parameter that characterizes the range of values within which the true value of a measurement lies.
- Intermediate Check: A verification process performed between calibrations to ensure continued accuracy.
4. References

8. Calibration Strategy
Calibration will follow the As Found then As Left logic. A minimum of 5 measurement points will be taken across the specified range of -40°C to 60°C, including endpoints and midpoints. Each point will have 3 replicate readings to ensure accuracy and reliability.
9. Step-by-Step Procedure
- Preparation: Gather all necessary tools and documentation.
- Stabilization: Allow the Temperature Data Logger to stabilize in the calibration environment.
- As Found Checks and Data Capture: Record initial readings at the defined points.
- Adjustment Rules: If any readings are OOT, escalate for adjustment as per SOP.
- As Left Verification: Record final readings after any adjustments.
- Labeling + Documentation Completion: Complete all required documentation and label the equipment accordingly.
Ensure all raw observations are recorded contemporaneously to maintain data integrity (ALCOA+).
10. Acceptance Criteria & Calculations
The acceptance criteria for the Temperature Data Logger is ±0.5°C. The error calculation formula is:
Error = Observed Value – True Value
Pass/Fail Logic: If the absolute value of the error is within the acceptance criteria, the calibration passes; otherwise, it fails.
Rounding Rule: [TBD]
11. Handling OOT / Failures
- Immediate containment: Tag the equipment and stop 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 after any necessary repairs or adjustments.
- QA Disposition Placeholders: [TBD]
12. Records & Retention
- Logbook entries must be maintained for all calibration activities.
- Calibration report/certificate filing must be done as per company policy.
- E-records if applicable: [TBD]
- Label Content Requirements: Calibrated date, due date, by whom, status.
