1.3 Warning and caution during measurement
Electric shock accident or malfunction
! Warning
●Check and confirm the cable condition and metal portion of the wire
before use. There is a danger of electric shock if the measuring cable is
broken or the metal portion of the wire is exposed. If some damage is
found, stop using it immediately and replace the specified new one.
●In order to prevent the electric shock accident or the failure of this unit,
do not apply voltage to the measurement terminal.
●In order to prevent the failure, conduct the measurement after turning off
the power related to the measurement.
●A high voltage is passed through the measuring cable. Never touch the
tip of the measuring cable to avoid the electric shock.
●In order to avoid electric shocks and to ensure the safety of the tester,
protective earth connection is necessary. Connect the supplied power
cord with ground insulating type bipolar outlet.
●When the tester is used, use the supplied power cord by the
manufacturer only. If the power cord not specified by manufacturer is
used, it may be the cause of fire.
Connection of the control cable and communication cable
! Caution
●Use the specified cable size to connect the control terminal.
●Make sure that communication cable and control cable are connected
surely. If the connection is not undertaken correctly, it may cause of the
failure to satisfy specification or malfunction.
●Power supply must be turned off on each device before connection of
communication cable and control cable. Failure to turn of the electric
power cause the electric shock or malfunction.
●Do not change the logic switching (PNP / NPN) of the control terminal
while the power supply is turned on. Set the logical switch (PNP / NPN)
suitable to the external device.
Other caution
! Caution
●If power supply is done by UPS（Uninterruptible power supply device)
or DC-AC inverter, do not use rectangular wave or pseudo rectangular
wave output of UPS or DC-AC inverter. If used, this may cause the
malfunction of the instrument.
●The power supply frequency setting is necessary to eliminate the
induced voltage of power supply. Setting the suitable power frequency
of the power supply in instrument before use.
