What is the purpose of calibration in GMP equipment?

• A. Ensure measurement accuracy and process control; maintain calibration schedules and records.
• B. To replace defective parts.
• C. To train staff.
• D. To document deviations.

Answer: (A)

Calibration in GMP equipment is about ensuring measurement accuracy so decisions based on those readings are reliable and the process stays under control. By regularly comparing an instrument’s output with a traceable standard and adjusting it as needed, you confirm that temperature, weight, pH, or other critical measurements truly reflect the process conditions. This reliability is essential for consistent product quality, food safety, and compliance with specifications and regulatory requirements. Keeping a documented calibration schedule and records provides traceability, supports investigations when issues arise, and helps plan preventive maintenance. Calibration isn’t about replacing parts, training staff, or merely recording deviations; those are separate GMP activities.
