Who ensures the test measuring equipment has current calibration stickers?

• A. Quality Assurance Investigator (QAI)
• B. Craftsman
• C. Control Material PO (CMPO)
• D. Department Head (DH)

Answer: (B)

Keeping test equipment in date with calibration is an operational responsibility handled by the person who maintains and uses the instrument. The craftsman performs routine upkeep and calibration, and after verifying the instrument’s accuracy, they apply or update the calibration sticker to show it’s current. That hands-on role ensures the equipment is ready for use and its measurements are trustworthy.

Quality Assurance Investigators focus on checking compliance and investigating issues, not performing routine calibrations or updating stickers. The Control Material PO handles procurement of control materials, not instrument calibration. The Department Head oversees broader department management but does not typically carry out calibration tasks or sticker updates.
