Risk of fatal injury
●
To avoid electric shock and short circuits, never attach the clamp to
bare, unisolated conductors.
Make sure to measure at a location on an insulated wire where the insu-
lation is sufficient for the circuit voltage.
●
Be careful to avoid damaging the insulation surface while taking mea-
surements.
●
Refer to the derating characteristics when measuring current that
includes a high-frequency component and never measure any current
that exceeds the rated current. Use with high frequencies or strong
magnetic fields may cause the device to become abnormally hot, result-
ing in fire, equipment damage, or burns.
●
To prevent fire or damage of the measurement target and device as well
as burns, exercise caution concerning the following when measuring
high-frequency currents or currents that contain high-frequency compo-
nents:
– Eddy current loss may cause heating of the sensor head.
– Dielectric heating may cause heating of cord insulation and other
materials.
●
Be sure to observe all operating precautions for the oscilloscope and
other instruments to which this device is connected.
Shock hazard
Do not allow the device to get wet, and do not take measurements with wet
hands. This may cause an electric shock.
To avoid electric shock when measuring live lines, wear appropriate protec-
tive gear, such as insulated rubber gloves, boots, and a safety helmet.
