Obtain an ohmmeter.
Detach the grounding cord from the wrist strap.
Measure the resistance between opposite ends of the grounding cord with
the ohmmeter. If you are not familiar with the use of this test equipment, see
manufacturer's intructions.
If resistance is
between 800 Ω ανδ 1200 Ω
not between 800 Ω ανδ 1200 Ω
The grounding cord and wrist strap assembly is safe to use. Assemble the
wrist strap to the grounding cord. Go to step 6.
DANGER
Risk of electrocution
The grounding cord is safe to use only if its resistance
measures higher than 800 Ω. A lower resistance exposes the
wearer to the risk of electrocution if equipment short circuits
while the wrist strap is being worn.
WARNING
Damage to electronic equipment
A grounding cord that has a resistance higher than 1200 Ω
cannot conduct static charges to ground adequately. It will
not protect sensitive electronic equipment against build-ups
of potentially damaging static charges.
Discard the entire assembly. Do not attempt to use it.
You have correctly completed this inspection procedure.
