Read the following safety information. (continued)
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 put on this instrument a container that water, medicine,
etc. has entered or a small metallic object.
If not, an electric shock or fire may occur. If this instrument is wet with water, or
metal and other objects enter the instrument, immediately remove this
instrument from the target to be measured, power off the equipment
connected with this instrument, and turn the POWER switch to the O side to
turn off the power to this instrument (remove the AC adaptor from the outlet
when used). After that, contact Iwatsu office or our sales distributors for repair.
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 office 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.
Insert the end of the Rogowski Coil into the joint hole to fix the
coil. 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.
