When performing monthly maintenance, you should verify what?

• A. Check power cords for fraying or wear
• B. Recalibration
• C. Replace battery
• D. Update software

Answer: (A)

Monthly maintenance focuses on safety and the physical condition of the device. The most important thing to verify is the power cords for fraying or wear. Damaged insulation or exposed conductors can cause electric shock or fire and may lead to sudden equipment failure. A quick check of cords, plugs, and strain relief helps prevent hazards and keeps the device safe for daily use.

Recalibration concerns accuracy and performance and is typically performed on a scheduled basis per manufacturer guidelines, not as a routine monthly safety check. Software updates are important but depend on the device and IT processes, so they aren’t inherently a monthly requirement. Replacing the battery depends on battery health and device design; not all devices require monthly battery changes, and replacement is guided by battery condition.
