Electrostatic Discharge (ESD) Module Practice Test 2026 - Free ESD Practice Questions and Study Guide

Grounding the device is the essential first step after an ESD event to prepare it for testing. By connecting the device to earth, any residual static charge is discharged and the device’s potential is equalized with the test equipment and environment. This creates a safe, stable baseline so subsequent tests aren’t influenced by leftover charge or risk triggering another discharge during handling. Once grounding is established, testing can proceed under controlled, repeatable conditions.

Inspecting for visible damage is important for identifying harm ESD may have caused, but it doesn’t remove charge or establish a safe testing baseline. Functional testing should follow grounding to avoid false results or additional damage. Implementing corrective actions to prevent recurrence belongs in the broader mitigation steps after the immediate testing setup is complete.
