3. Definitions
- Calibration: The process of verifying and adjusting the accuracy of an instrument.
- Verification: The confirmation that an instrument meets specified requirements.
- Adjustment: The act of correcting an instrument to ensure it operates within specified limits.
- 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 instrument readings fall outside the specified acceptance criteria.
- Drift: The gradual change in an instrument’s accuracy over time.
- Traceability: The ability to trace the measurement 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 verification process performed between calibrations to ensure ongoing accuracy.
4. References

8. Calibration Strategy
Calibration will follow the As Found and As Left logic. A minimum of 5 calibration points will be taken, including endpoints (20°C and 300°C) and midpoints. Each point will have 3 replicate readings to ensure accuracy.
9. Step-by-Step Procedure
- Preparation: Gather all necessary tools and standards.
- Stabilization: Allow the equipment to reach operating conditions.
- As Found checks and data capture: Measure temperature at defined points and record data contemporaneously.
- Adjustment rules: If OOT is detected, adjust the equipment if permitted; otherwise, escalate the issue.
- As Left verification: Measure again to confirm adjustments are within acceptance criteria.
- Labeling + documentation completion: Ensure all records are completed and labeled appropriately.
10. Acceptance Criteria & Calculations
Acceptance criteria for the Magnetic Stirrer Hotplate Temp is ±2°C. The error calculation formula is:
Error = Observed Value – True Value
Pass/Fail Logic: If the absolute value of the error is within ±2°C, the calibration passes; otherwise, it fails.
Rounding rule: [TBD]
11. Handling OOT / Failures
- Immediate containment: Tag equipment and cease use.
- Notification & deviation initiation: Notify relevant personnel of the OOT condition.
- Impact assessment trigger: Review affected results/batches within the defined impact window.
- Recalibration after repair/adjustment: Ensure recalibration is performed post-adjustment.
- QA disposition placeholders: [TBD]
12. Records & Retention
- Logbook entries must be made for each calibration.
- Calibration report/certificate filing must be maintained.
- E-records if applicable: [TBD]
- Label content requirements: calibrated date, due date, by whom, status.
