Safety Summary

Electrostatic Discharge (ESD)

Welch Allyn Spot Vital Signs LXi

Electrostatic discharge is a sudden current flowing from a charged object to another object or to ground. Electrostatic charges can accomulate on common items such as foam drinking cups, cellophane tape, synthetic clothing, untreated foam packaging material, and untreated plastic bags and work folders, to name only a few.

Electronic components and assemblies, if not properly protected against ESD, can be permanently damaged or destroyed when near or in contact with electrostatically charged objects. When you handle components or assemblies that are not in protective bags and you are not sure whether they are static-sensitive, assum that they are static-sensitive and handle them accordingly.

• Perform all service procedures in a static-protected environment. Always use techniques and equipment designed to protect personnel and equipment from electrostatic discharge.

• Remove static-sensitive components and assemblies from their static-shielding bags only at static-safe workstations - a properly grounded table and grounded floor mat - and only when you are wearing a grounded wrist strap (with a resistor of at least 1 megohm in series) or other grounding device.

• Use only grounded tools when inserting, adjusting, or removing static-sensitive components and assemblies.

• Remove or insert static-sensitive components and assemblies only with monitor power turned off.

• Insert and seal static-sensitive components and assemblies into their original staticshielding bags before removing them from static-protected areas.

Always test your ground strap, bench mat, conductive work surface, and ground cord before removing components and assemblies fromtheir protective bags and before beginning any disassembly or assembly procedures.
