How often should instruments be checked for calibration drift?

How often should instruments be checked for calibration drift?

• A. Only before initial use
• B. Periodically, based on usage and manufacturer recommendations
• C. Once every five years
• D. After significant environmental changes only

Answer: (B)

Instruments should be checked for calibration drift periodically, based on usage and manufacturer recommendations. This is important because instruments can experience changes in their accuracy over time due to various factors such as wear and tear, environmental conditions, and the frequency of use. Regular checks ensure that the instruments maintain their performance within acceptable limits, which is crucial for reliability in measurement and control processes. Manufacturer recommendations often provide specific guidelines on how often checks should be conducted, taking into account the specific application, the instrument's sensitivity, and the conditions under which it operates. By adhering to these guidelines, users can avoid potential errors that could arise from instruments drifting out of calibration, thereby maintaining safety and efficiency in operations.
