3. Definitions
- Calibration: The process of comparing a measurement device to a known standard to determine its accuracy.
- Verification: The process of confirming that a measurement device operates within specified limits.
- Adjustment: The act of correcting a measurement device to bring it within specified limits.
- As Found: The condition of the equipment prior to any adjustments made during calibration.
- As Left: The condition of the equipment after calibration adjustments have been made.
- OOT (Out of Tolerance): A condition where the measurement falls outside the specified acceptance criteria.
- Drift: The gradual change in a measurement device’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 that characterizes the dispersion of the values attributed to a measurement.
- Intermediate Check: A periodic check performed between calibrations to ensure continued accuracy.

8. Calibration Strategy
Calibration will follow the As Found and As Left logic. The minimum number of test points will be five, including endpoints and midpoints within the range of 0 to 16 bar. It is recommended to take three replicate readings at each point to ensure accuracy.
9. Step-by-Step Procedure
- Preparation: Gather all necessary tools and reference standards.
- Stabilization: Allow the pressure gauge to stabilize before taking measurements.
- As Found Checks and Data Capture: Record initial measurements and document them contemporaneously.
- Adjustment Rules: If OOT is detected, follow the adjustment protocol; otherwise, escalate the issue.
- As Left Verification: After adjustments, verify and document the final measurements.
- Labeling + Documentation Completion: Complete all required documentation and label the equipment accordingly.
10. Acceptance Criteria & Calculations
The acceptance criteria for the calibration of the Water System Pressure Gauge is ±1%. The error calculation formula is:
Error (%) = (Observed Value – True Value) / True Value × 100
Pass/Fail Logic: If the calculated error is within ±1%, the gauge 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 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 of calibration certificates.
- e-Records if applicable: [TBD]
- Label content requirements: Include calibrated date, due date, technician name, and status.
