- Department/Area: Production / Dispensing
- Process Use: Material dispensing
- Parameter: Weight
- Range: 0 g to 15000 g
- Units: g
- Calibration Frequency: 365 days
3. Definitions
- Calibration: The process of comparing a measurement device to a known standard to ensure 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 state of the equipment before any adjustments are made.
- As Left: The state of the equipment 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 a measurement device’s performance 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 is asserted to lie.
- Intermediate Check: A periodic check of the measurement device to ensure it remains within specified limits.
4. References

5. Responsibilities
- Technician/Metrology: Perform calibration and document results.
- QC/QA Reviewer: Review calibration documentation for compliance.
- Owner Department: Ensure equipment is available and in proper 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 equipment to warm-up and stabilize as per manufacturer guidelines.
- Maintain cleanliness of the balance and surrounding area.
- Check that the balance is level before use.
- Verify power supply is stable and within specifications.
7. Standards & Tools
- Reference standards required: Calibration weights (certified).
- Traceability: ISO17025
- Check certificate validity of reference standards prior to use.
- Standard ID: [TBD]
8. Calibration Strategy
The calibration will follow an As Found then As Left logic. The minimum number of points for calibration will be five, including endpoints and midpoints of the specified range (0 g to 15000 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 reference standards.
- Stabilization: Allow the balance to warm up for at least [TBD] minutes.
- As Found checks and data capture: Measure and record the weight using certified calibration weights.
- Adjustment rules: If OOT is detected, follow the adjustment protocol or escalate to QA.
- As Left verification: Re-measure to confirm adjustments bring the balance within acceptance criteria.
- Labeling + documentation completion: Complete all required documentation and label the equipment with calibration details.
Record all raw observations contemporaneously to ensure data integrity (ALCOA+).
10. Acceptance Criteria & Calculations
The acceptance criteria for the Top Loading Balance 0.1 g is ±0.1 g. 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 QA and initiate a deviation report.
- Impact assessment trigger: Review affected results/batches within the defined impact window.
- Recalibration after repair/adjustment: Ensure recalibration is performed post-adjustment.
- QA disposition: [TBD]
12. Records & Retention
- Logbook entries: Document all calibration activities.
- Calibration report/certificate filing: Maintain records for audit purposes.
- e-Records if applicable: [TBD]
- Label content requirements: Include calibrated date, due date, technician name, and calibration status.
