Calibration SOP

1. Purpose

The calibration of the Lux Meter is performed to ensure accurate measurement of illumination levels within the facility. This calibration controls risks related to data integrity and ensures compliance with operational standards, thereby supporting batch quality and overall process reliability.

2. Scope

  • Asset ID: CAL-0261
  • Equipment Name/Type: Lux Meter
  • Department/Area: Engineering
  • Process Use: Illumination
  • Parameter: Lux
  • Range: 0 – 20000 lux
  • Units: lux
  • Calibration Frequency: 365 days

3. Definitions

  • Calibration: The process of comparing a measurement instrument against a 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 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 accuracy 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 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 of the instrument’s performance between calibrations.

4. References

  • Company Metrology SOP [TBD]
  • ISO/IEC 17025 traceability via calibration certificates
  • ALCOA+ principles

5. Responsibilities

  • Technician/Metrology: Perform calibration and maintain records.
  • QC/QA Reviewer: Review calibration records and ensure compliance.
  • Owner Department: Ensure the equipment is available and in good condition for calibration.
  • External Service Provider: Conduct external calibration as per the defined schedule.

6. Safety & Preconditions

  • Ensure environmental controls are in place (temperature, humidity).
  • Allow for warm-up/stabilization of the Lux Meter as per manufacturer specifications.
  • Maintain cleanliness of the equipment and surrounding area.
  • Check leveling of the Lux Meter before use.
  • Verify power supply stability and integrity.

7. Standards & Tools

  • Reference Standards: [TBD]
  • Traceability Statement: ISO17025
  • Certificate Validity Check: Ensure calibration certificates are current and valid.

8. Calibration Strategy

Calibration will follow the As Found and As Left logic:

  • Minimum number of points: 5 points including endpoints (0, 5000, 10000, 15000, 20000 lux).
  • Replicate readings at each point: 3 repeats as a best practice.

9. Step-by-Step Procedure

  1. Preparation: Gather all necessary tools and documentation.
  2. Stabilization: Allow the Lux Meter to stabilize as per manufacturer guidelines.
  3. As Found checks and data capture: Record initial readings at specified points.
  4. Adjustment rules: If OOT is identified, follow adjustment procedures if permitted; otherwise, escalate to QA.
  5. As Left verification: Record final readings after adjustments.
  6. Labeling + documentation completion: Ensure all records are filled out accurately.

Explicit instruction: Record raw observations contemporaneously to ensure data integrity (ALCOA+).

10. Acceptance Criteria & Calculations

Acceptance criteria: ±5% of the measured value.

Error calculation formula: Error (%) = (Measured Value – True Value) / True Value × 100

Pass/Fail logic: If the error falls within ±5%, the calibration passes; otherwise, it fails.

Rounding rule: [TBD]

11. Handling OOT / Failures

  • Immediate containment: Tag equipment and stop use.
  • Notification & deviation initiation: Inform relevant stakeholders.
  • Impact assessment trigger: Define impact window and review of affected results/batches.
  • Recalibration after repair/adjustment: Schedule recalibration as necessary.
  • 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: Calibrated date, due date, by whom, status.
