What is a key benefit of automated self-checks in calibration procedures?

• A. They have no impact on accuracy
• B. They slow down device startup
• C. They increase wear and tear
• D. They reduce the need for manual recalibration and help detect drift

Answer: (D)

Automated self-checks during calibration are about keeping measurement accuracy over time by routinely verifying performance and catching drift or bias early. The main benefit is that they reduce the need for manual recalibration and help detect drift promptly, which maintains reliability and consistency without lengthy manual inspections. This also frees technicians to focus on other tasks and minimizes unexpected downtime caused by undetected drift.

As for the other ideas: automated checks do contribute to maintaining accuracy, not leaving it unchecked. They aren’t primarily about slowing everything down; if anything, they streamline calibration by flagging issues early and avoiding big surprises during setup. And they don’t generally cause more wear and tear—self-checks rely on internal references and checks rather than physical wear, and they can reduce wear by avoiding unnecessary manual adjustments.
