What must you do prior to performing electrical testing following an electronic equipment repair action?

Prior to performing electrical testing after an electronic equipment repair action, conducting a visual inspection is crucial. This step allows you to check for any obvious signs of damage, such as loose connections, burned components, or incorrect assembly that may have occurred during the repair process. A thorough visual inspection ensures that everything appears as it should before applying power to the device, potentially preventing further damage or unsafe conditions.

Engaging in a visual inspection first serves as a fundamental step in troubleshooting. This practice is a standard procedure to ensure the safety of both the technician and the equipment. It allows for the identification of potential issues that may not be apparent through testing alone, making it an essential preliminary action. Conducting subsequent steps such as power cycling the device, checking the software status, or testing voltage levels without first performing this visual assessment could lead to inaccuracies in diagnosis or even pose safety risks.
