172 5977B Series MSD Operating Manual
When you work on or near printed circuit boards or when you work on
components with wires, contacts, or cables connected to printed circuit boards,
always use a grounded antistatic wrist strap and take other antistatic
precautions. The wrist strap should be connected to a known good earth ground.
If that is not possible, it should be connected to a conductive (metal) part of the
assembly being worked on, but
not to electronic components, exposed wires or
traces, or pins on connectors.
Take extra precautions, such as a grounded antistatic mat, if you must work on
components or assemblies that have been removed from the MSD. This
includes the analyzer.
To be effective, an antistatic wrist strap must fit snugly (not tight). A loose
strap provides little or no protection.
Antistatic precautions are not 100% effective. Handle electronic circuit boards
as little as possible and then only by the edges. Never touch components,
exposed traces, or pins on connectors and cables.
