To prevent an electrical shock hazard to the operator and/or damage to the instruments, read this
instruction manual carefully before using the Insulation Tester. WARNINGS with the symbol
on the Insulation Tester and this instruction manual are highly important.
FOR SAFETY MEASUREMENTS
WARNING
Do not measure High Power Line (High Energy Circuits). High Power Line is
very dangerous and sometimes includes High Surge Voltage that could
cause explosive short in the instrument and could result in serious injury to
the operator. This instrument is for Low Power Line measurement. Even in
the Low Power Line, pay careful attention when measuring high voltage line.
The symbol listed in IEC 61010-1 and ISO 3864 means "Caution (refer to
instruction manual)".
The symbol in this manual advises the user of an electrical
shock hazard that could cause injury or material damages.
The symbol in this manual advises the user of an electrical
shock hazard that could result in serious injury or even death.

3. SAFETY PRECAUTIONS
Correct knowledge of electric measurements is essential to avoid unexpected danger such as
operator's injury or damage to the instrument. Read the following precautions carefully for safety
measurements.
Before measurement, check if there are no damage to the instrument and the test leads. Dust,
grease and moisture must be removed.
3-1. Warnings
WARNING 1. Checks of the Instrument and Test Leads
WARNING 2. Prohibition of High Power Line Measurement
Do not measure High Power Line (High Energy Circuits) such as Distribution Transformers, Bus
Bars and Large Motors. High Power Line sometimes includes High Surge Voltage that could
cause explosive short in the instrument and could result in shock hazard. Generally, shock hazard
could occur when the current between the circuit, that involves more than 30V AC or 42.4V DC,
and ground goes up to 0.5mA or more.

- 5 -
Even for Low Power Circuits of electric/electronic appliances, such as heating elements, small
motors, line cords and plugs, High Voltage Measurements are very dangerous. To avoid electric
shock hazard, pay careful attention not to touch any part of the circuit.
WARNING 3. Warning for High Voltage Measurement
WARNING 4. Warning for Dangerous Voltage Measurement
●Do not hold the instrument in your hands.
●Keep safety distance from the circuit to be measured and the test leads not to touch the
dangerous voltage.
●Attach black and red alligator clips to the test lead pins.
●Turn off the circuit to be measured when connecting the test leads.
●After finishing the measurement, turn off the circuit to be measured again and discharge the
all capacitors. Then, detach alligator clips (test leads) from the circuit.
For dangerous high voltage measurement, strictly observe the warnings below (see Fig. 1).
In case of live-line measurement, strictly observe the warnings below (see Fig. 2) :
●Do not hold the instrument in your hands.
●Keep safety distance from the circuit to be measured not to touch the dangerous voltage.
●Black test lead : Attach black alligator clip and connect to −(earth) side of the circuit.
●Red test lead : Connect to ＋(positive) side of the circuit.

WARNING 6. Correct Function Settings
Children and the persons who do not have enough knowledge about
electric measurements must not use this instrument.
Do not measure the electricity in naked of barefooted to protect yourself
from electrical shock hazard.
Be careful not to get hurt with the sharp test lead pins.
Keep away the instrument from hot and humid conditions like in the car.
Do not apply hard mechanical shock or vibration.
Do not polish the case or attempt to clean it with any cleaning fluid like
gasoline or benzine. If necessary, use silicon oil or antistatic fluid.

CAUTION 2.
3-3. General Warnings and Cautions
Do not measure any elements that might exceed the specified maximum input values of each
measurement ranges.
Always confirm that the correct measurement function is selected. Do not measure any voltage
except in the Voltage (V) function.
3-2. AC Adapter
Do not place high frequency welding machine or equivalent near the power source. The noise
might affect the instrument and would cause the mechanical error.
Read the following precautions carefully to prevent electric shock, fire accident, or damage to
the instrument
●Be sure to use with the specified power supply voltage.
●Insert the power plug and the connector fully into the each sockets.
●Do not pull the power cord when removing the power plug from the socket.
●Always keep the power plug and connector clean.
●Do not insert and remove the power plug and the connector with the wet hand.
●Do not damage, bend hardly, pinch, compress, or modify the power cord.
●Do not apply mechanical shock to the adapter part. Do not drop it off.
●Do not use the power cord that has any damage or melted coating.
