Read the following safety information. (continued)
WARNING

Do not use this instrument in an environment with explosive
gases.
Failure to do so may cause an explosion.

Avoid the generation of Corona discharge in an environment
where high voltage is applied to the sensor part for a long time.
Depending on the frequency of the applied voltage and installation conditions
of the sensor part, Corona discharge may be generated even when a voltage
lower than resisting voltage is applied to the sensor part. This generation may
lead to degrading the insulating outer sheath, causing an electrical shock,
fire, or failure.
Corona discharge tends to be generated due to electric field concentration.
Take some measures to avoid the generation; for example, keep the sensor
part away from high-voltage parts as far as possible or achieve insulation.

Do not use this instrument in a highly humid environment where
condensation may occur.
If not, an electric shock, fire, or failure may occur.

When thunder begins, pull out the power plug of a device or the
AC adaptor to which this instrument is connected from the outlet.
Then, detach this instrument from the target to be measured, and
do not use it.
Lightning may be a cause of an electric shock, fire, or failure.

Do not use this instrument when it has failed.
Using a failed main unit, cable or AC adaptor may be a cause of an electric
shock or fire. In the event of a failure, contact IWATSU or our sales
distributors for repair.

Turn off the power to the target to be measured before attaching
or detaching the Rogowski Coil Sensor part of this instrument to
or from the target to be measured.
Failure to do so is very dangerous for targets to be measured that use high
voltage and high current.

Be sure to use the free end of the Rogowski Coil while inserted in
the joint hall. Do not apply a high voltage exceeding the
specifications (refer to Section 5.1 “Specifications”) to the
Rogowski Coil Sensor.
Failure to do so may cause an electric shock, fire, or failure.

The sensor cable cannot be removed because it is integral with
(connected inside of) the main unit. Do not attempt to disconnect
the sensor cable.
Failure to do so may cause an electric shock, fire, or failure.
