Obtain an ohmmeter.
Take the grounding cord off the wrist strap.
Measure the resistance between opposite ends of the grounding cord with
the ohmmeter.
If resistance is
between 800 kΩ ανδ 1200 κΩ
not between 800 kΩ ανδ 1200 κΩ
You can use the grounding cord and wrist strap assembly. Assemble the wrist
strap to the grounding cord.
Go to step 6.
DANGER
Risk of electrocution
The grounding cord is only safe to use if the resistance of the
grounding cord measures higher than 800 kΩ. Lower
resistance exposes the wearer to the risk of electrocution.
Electrocution can occur if equipment short-circuits while the
user wears the wrist strap.
WARNING
Damage to electronic equipment
A grounding cord that has a resistance higher than 1200 kΩ
cannot conduct enough static charges to ground correctly.
The grounding cord will not protect sensitive electronic
equipment against build-ups of static charges that can cause
damage.
Discard the complete assembly. Do not attempt to use it.
The procedure is complete.
