1.6Precautions for use
In order to use the instrument safely and make full use of its functions, please observe the
following precautions.
1.6.1 Inspection before use
Warning
•If the test cable or the instrument is damaged, it may cause electric
shock. Be sure to do the following checks before using it.
•Before using it, please confirm that there are no problems caused
by storage and transportation, and use it after checking and
confirming the operation. If it is confirmed to be faulty, please
contact the agent or the company after-sales center.
•The outer surface of the power cord damage or exposure may
cause an electric shock or short circuit accident. Please do not use,
and contact your dealer or company after-sales center
•The outer skin of the cable damage or metal exposure may cause
short circuit or electric shock. Please replace with a device that is
not damaged.
•Check whether the instrument is damaged. If it is damaged, please
send it for repair.
•When the power is turned on and the start button is lit red, the
power cord may be broken or a malfunction occur inside the
instrument. Please send it for repair.
•After the end of the test (displaying the company LOGO), if the
main measurement function screen is not displayed, a malfunction
may occur inside the instrument. Please send it for repair.
1.6.2 Placement environment
Warning
Please do not place the instrument in the following places,
otherwise it will cause malfunction or accident of the instrument.
•Direct sunlight or high temperature places
•Locations where corrosive gases and explosive gases are
generated
•Places where strong electromagnetic waves are generated
or near charged objects
•Close to induction heating device (high frequency
induction heating device, IH induction cooker, etc.)
•Locations where mechanical vibrations are frequent
•Locations affected by water, oil, chemicals and solvents
•Wet, dew condensation
•A place with a lot of dust

9
1.6.3 Placement method
Warning
Please do not place on unstable pedestals or in inclined places.
Otherwise, personal injury or malfunction of the main unit may occur
due to falling or tipping over.
•Place the bottom side down.
•In order to prevent the temperature of the instrument from rising,
please be sure to keep a specified distance from the surroundings
when placing it.
Above 50mm Above 50mm Above 150mm
The means to cut off the power supply of this instrument is to unplug the power cord. In
case of emergency, the power cord can be unplugged to cut off the power supply
immediately, so please make sure that there is enough space for operation.
1.6.4 Use of the instrument
Danger
To prevent an electric shock, never remove the main unit casing, since
there are high voltage and high temperature parts inside.
Note
In order to prevent damage to the instrument, please avoid vibration
and collision during handling and use, and pay attention to collisions
caused by falling.
1.6.5 Before connecting the power cord
Warning
To avoid electric shock and to ensure the safety of this instrument,
please connect the supplied power cord to a three-phase outlet.

10
1.6.6 Before connecting the test cable
Danger
Be sure to connect the test cable to the secondary side of the circuit
breaker. Even if a short circuit occurs on the secondary side of the
circuit breaker, the short circuit current is cut by the circuit breaker. The
current capacity on the primary side is very large, and in the event of a
short circuit accident, damage to the instrument or equipment may
occur.
Warning
To avoid electric shock and short circuit accidents, please use the
specified test cable.
1.6.7 Before turning on the power
Warning
Before turning on the power, please confirm whether the power
voltage listed on the power connection of the instrument and the one
you are using are consistent.
Using the power supply voltage outside the specified range may cause
instrument damaged or an electrical accident.
Note
Do not use UPS and DC-AC inverters with square wave or
approximate sine wave output to drive this instrument to avoid damage
to this instrument.

11
1.6.8 Before measurement
When measuring voltage
Danger
•The maximum in-phase voltage of the voltage measurement terminal
is as follows.
CAT II: AC/DC 300 V
Without measurement classification:AC/DC 800 V
Exceedance of this voltage may cause damage to the instrument or
cause personal injury.
•The maximum input voltage of the voltage measurement terminal is
DC 1000 V and 1100 V peak.
When the voltage exceeds 800V, it can be measured only when the
object to be tested is insulated from the ground. Exceedance of this
voltage may cause damage to the instrument or personal injury.
•To prevent an electric shock, do not use the test cable tip to avoid
short circuit in the voltage-applied circuit.
1.6.9 Before connecting the communication cable
Note
When connecting or removing the communication cable, please be
sure to turn off the power of the instrument and the connected device.
Failure to do so may result in false action or malfunction.
