Which activity is categorized as function verification?

• A. Preventive maintenance
• B. Quality control
• C. Function verification
• D. Precision verification

Answer: (C)

Function verification is about proving that an instrument can perform its essential tasks and respond correctly to inputs before use or after maintenance. It checks that the main operations—startup, software and interface functions, control commands, data output, and safety alarms—work as intended. This focus on whether the device can carry out its required functions distinguishes it from preventive maintenance (routine upkeep to prevent failures), quality control (using control materials to ensure results are within acceptable ranges), and precision verification (assessing repeatability and precision of measurements). So, the activity described is function verification because it centers on confirming the instrument’s ability to perform its intended functions.
