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 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 necessary adjustments.
- OOT (Out of Tolerance): A condition where the measurement results fall outside the specified acceptance criteria.
- Drift: The gradual change in a measurement 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 that characterizes the range of values within which the true value of a measurement lies.
- Intermediate Check: A verification process conducted between calibrations to ensure continued accuracy.

- Maintain cleanliness of the calibration area and equipment.
- Check leveling of the equipment.
- Verify power supply stability.
7. Standards & Tools

- Traceability: ISO17025
- Certificate validity check: Ensure calibration certificates are current and valid.
- Standard ID placeholders: [TBD]
8. Calibration Strategy
Calibration will follow the As Found and As Left logic. The minimum number of points for calibration will be five, including endpoints and midpoints within the range of 1 g to 1000 g. 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 documentation.
- Stabilization: Allow the equipment to stabilize in the calibration environment.
- As Found checks and data capture: Measure and record the weight of each standard weight.
- Adjustment rules: If any measurements are OOT, escalate for adjustment as per SOP.
- As Left verification: Measure and record the weight of each standard weight post-adjustment.
- Labeling + documentation completion: Label the equipment and complete all required documentation.
Record all raw observations contemporaneously to ensure data integrity (ALCOA+).
10. Acceptance Criteria & Calculations
The acceptance criteria for the Standard Weights Set F2 is F2 Class. The error calculation formula is as follows:
Error = (Observed Value – True Value) / True Value x 100%
Pass/Fail logic: If the error is within the acceptance criteria, the calibration passes; otherwise, it fails.
Rounding rule: [TBD]
11. Handling OOT / Failures
- Immediate containment: Tag equipment and stop use.
- Notification & deviation initiation: Notify relevant personnel and initiate deviation process.
- Impact assessment trigger: Define impact window and review of affected results/batches.
- Recalibration after repair/adjustment: Ensure recalibration is performed after any adjustments.
- 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, by whom, and status.
