WARNING
●In measurement with this instrument, high voltage
may be applied and high current may be supplied.
Always close the cover before measurement after
setting the DUT (Device Under Test) on the Test Fix-
ture. Also, do not open the Test Fixture cover dur-
ing measurement.
High voltage (max. 5 kV) may be applied and high current (max. 2 kA) may be supplied to the ter-
minal to which the DUT is mounted. To prevent danger, if the cover of the Test Fixture is not closed,
no voltage and current can be supplied to the terminal and no power can be applied to the DUT.
And, do not remodel the switch for power supply shutoff or do not open the cover during measure-
ment. If not, electric shock may be caused. When it is detected that the cover of the Test Fixture is
opened during measurement, the supply of voltage and current to the terminals is immediately cut
off, and the energization of the DUT is stopped. For your safety, do not open the cover during meas-
urement.
●After the measurement is completed, the meas-
urement DUT may be charged and generate heat.
Never touch the measurement DUT until you can dis-
charge it with a grounding rod, take measures
against heat, and confirm the safety.
Touching a charged or generated measurement DUT may cause electric shock or burns. Take
measures such as using gloves, antistatic measures, and leaving the instrument for a suffi-
cient period of time.
●When using anything other than the test wire
lead or small crocodile that comes with the Test
Fixture, pay attention to the withstand voltage
and allowable current.
If the measurement is performed without considering the measurement potential, cable outer insula-
tion, and GND cable outer insulation rating, it may cause a fire or malfunction. Use the specified cable
that comes with the Test Fixture according to the measurement content.
●Always use the interlock function.
Connect the interlock circuit to the INTERLOCK connector of this instrument. Also, check regularly
that the interlock function is working properly.
Make sure that the interlock lamp (indicator LED) is lit when setting the DUT. Also, turn OUTPUT
ENABLE OFF (indicator LED is off).
