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
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.
In order 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
CA UT IO N
as possible and then only by the edges. Never touch the components, exposed traces,
or pins on connectors and cables.
