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 1.

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.

●When taking the comparator measurement with the input terminals are opened, such as when

the resistance measurement, comparator always shows "Hi" result with "OL" sign on LCD. To

prevent this problem, add GO/STOP signal to your inspection system in reference to the circuit

diagram shown in Fig. 11.

7. MAINTENANCE

●To avoid electrical shock hazard, finish the measurement when to replace the fuse.

●Detach test leads from measuring circuit and input terminals and disconnect AC Adapter

from power source.

●Always use the specified fuse. Do not use this instrument shorting fuse holder or

without using the fuse.

Detach test leads from measuring circuit and

input terminals and disconnect AC Adapter

from power source.

Remove 4-screws from the legs on the

bottom case and remove 2-legs on rear

panel side.

Remove the top case.

Replace the blowout fuse into the new one.
NOTE : Verify that the correct rating fuse is

used.

Fix the top case and the removed legs and

tighten the screws.
