Pre-Operation Inspection
Before use, verify that test lead insulation is
„
not torn and that no metal is exposed.
Before use, inspect the instrument and verify
„
that it's operating properly.
Use of the instrument while it is malfunctioning could
result in serious bodily injury. If you find any damage,
contact your authorized Hioki distributor or reseller.
Before measuring
Do not apply voltage to the measurement
„
terminals.
Doing so could cause damage to the instrument or
electric shock accidents.
Perform measurements after turning off the
„
power to the measurement targets being
measured.
Doing so could cause an electrical hazard.
Precautions during measurement
Do not use the instrument for measurements
„
on circuits that exceed the ratings or
specifications of the instrument.
Doing so could cause damage to the instrument or
overheating, resulting in serious bodily injury.
Providing power to the instrument
Connect the power cord to a grounded, two-
„
prong power outlet.
Connecting the product to an ungrounded power
outlet could cause the operator to experience an
electric shock.
Ensure that the insulation on the cables are
„
undamaged and that no bare conductors are
improperly exposed before use.
Any damage to the instrument leads to electric shock.
Contact your authorized Hioki distributor or reseller.
Before connecting the power cord, make
„
sure the supply voltage to be used falls
inside the voltage range indicated on the
power connector of the instrument.
Supplying a voltage that falls outside the specified
range to the instrument could damage the instrument,
causing bodily injury.

Measurement leads
Do not use test leads whose insulation is
„
damaged or whose metal portion is exposed.
Doing so could cause serious bodily injury.
Do not short wires carrying a voltage with
„
the tips of the test leads.
Doing so could cause a short-circuit, resulting in
serious bodily injury.
When using the instrument while connected
„
to test leads, use the lower of the ratings
indicated on the instrument and on the test
leads.
Using the product to make measurements that exceed
either rating could cause the operator to experience
an electric shock.
Cut off power to measurement lines before
„
connecting them to measurement terminals.
Failure to do so this can cause electric shock or a
short-circuit.
The analog output thermometer
Since the temperature measurement circuit
„
is grounded, connect the TEMP.ANALOG
INPUT terminal on the rear panel with the
analog output thermometer isolated from the
ground.
Failure to do so could cause the operator to
experience an electric shock or damage the
instrument.
The multiplexer unit
See: Instruction Manual "2.5 Installing the Multiplexer Unit"
and "7 Multiplexer"
Turn off the product and disconnect any
„
cables before inserting or removing any
multiplexer unit.
Failure to do so could cause the operator to
experience an electric shock or damage the
instrument or multiplexer unit.
When connecting a measurement target
„
with electromotive force (a battery or power
supply), take steps to protect against short-
circuits.
Failure to do so could cause damage to the instrument
or measurement targets or cause fire.
If not connecting a multiplexer unit, attach
„
the blank panel.
Failure to do so could cause the operator to
experience an electric shock or damage the
instrument.
