Monthly maintenance tasks typically include which of the following?

• A. Check power cords for fraying or wear
• B. Recalibration
• C. Replace fuse
• D. Update user manual

Answer: (A)

Monthly maintenance focuses on safety and preventing equipment issues. A practical and quick monthly check is inspecting power cords for signs of fraying, cracking insulation, or damaged connectors. Damaged cords can cause electric shock, short circuits, or fire, so catching wear early helps prevent bigger problems and downtime. Recalibration is typically needed when instrument accuracy drifts or after a service event, not as a routine monthly task. Replacing a fuse is done only when a fuse has blown or is defective, which isn’t a monthly routine activity. Updating the user manual is an information task and not part of keeping the device functioning day to day. For these reasons, checking power cords for wear is the most appropriate monthly maintenance item.
