  • Equipment Name/Type: Differential Pressure Transmitter / DP Transmitter
  • Department/Area: HVAC / Cleanroom
  • Process Use: Room DP
  • Parameter: Differential Pressure
  • Range: 0 – 500 Pa
  • Units: Pa
  • Calibration Frequency: 180 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 calibration.
  • As Left: The condition of the instrument after calibration.
  • 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 measurement results back to national or international standards.
  • Measurement Uncertainty: A parameter that characterizes the range of values within which the true value is expected to lie.
  • Intermediate Check: A periodic check performed between calibrations to ensure continued accuracy.

4. References

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

8. Calibration Strategy

Calibration will follow the As Found and As Left logic. A minimum of 5 calibration points will be established, including endpoints and midpoints within the specified range of 0-500 Pa. It is recommended to take 3 replicate readings at each point to ensure accuracy and reliability.

9. Step-by-Step Procedure

  1. Preparation: Gather all necessary tools and reference standards.
  2. Stabilization: Allow the transmitter to stabilize as per manufacturer guidelines.
  3. As Found checks and data capture: Record initial readings and document results contemporaneously (ALCOA+).
  4. Adjustment rules: If OOT is detected, follow escalation procedures as adjustments may not be permitted.
  5. As Left verification: Confirm that the transmitter is within tolerance after any adjustments.
  6. Labeling + documentation completion: Ensure all calibration records are filled out accurately and completely.

10. Acceptance Criteria & Calculations

The acceptance criteria for the calibration of the Differential Pressure Transmitter is ±5 Pa. 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 cease use.
  • Notification & deviation initiation: Notify relevant personnel of the OOT condition.
  • 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.
