Alternatively, obtain and wear a commercially available discharging wrist strap device, which should be removed for potential shock reasons prior to applying power to the unit under test. 2. After removing an ele

These can generate electrical change sufficient to damage ES devices. 6. Do not remove a replacement ES device from its protective
