TWO TYPES OF CALIBRATION

Описание: In this video, we explain the difference between As Found and As Left calibration results — two critical concepts in measurement and quality control.

Understanding these terms is essential for:
• Determining the true condition of an instrument before adjustment
• Documenting measurement error for traceability
• Supporting audit and compliance requirements
• Maintaining proper calibration records

As Found results show the instrument’s performance before any adjustment, while As Left results show its condition after calibration or correction.

Proper documentation of both is important in quality systems such as ISO/IEC 17025 and ISO 9001, and helps ensure measurement reliability in industrial and laboratory environments.

If you work in calibration, QA, QC, or maintenance, this explanation will help strengthen your understanding of proper calibration reporting.
