Obtain an ohmmeter.
DANGER
Risk of electrocution
The grounding cord is safe to use if resistance
measures higher than 800 kohms. A lower resistance
exposes the wearer to the risk of electrocution if
equipment short-circuits.
WARNING
Damage to electronic equipment
A grounding cord that has a resistance higher than
1200 kohms cannot conduct enough static charges to
ground. The cord does not protect sensitive electronic
equipment against build-ups of static charges that can
cause damage.
Detach the grounding cord from the wriststrap.
Measure the resistance between opposite ends of the grounding cord with the
ohmmeter.
If resistance
is between 800 kohms and 1200 kohms
is not between 800 kohms and 1200 kohms
Use the grounding cord and wriststrap assembly. Assemble the wriststrap to
the grounding cord. Go to step 6.
Discard the assembly. Do not use the assembly.
The procedure is complete.
