To prevent an electrical shock hazard to the operator and/or damage to the
instruments, read this instruction manual carefully before using the Clamp
Meter. WARNINGS with the symbol on the Clamp Meter and this
instruction manual are highly important.

Important Symbols

The symbol listed in IEC 61010-1 and ISO 3864 means "Caution
(refer to instruction manual)".

WARNING : The symbol in t his manual advises the user of an
electrical shock hazard that could result in serious injury or even
death.

CAUTION : The symbol in this manual advises the user of an
electrical shock hazard that could cause injury or material damages.

Measurement on High Power Line is very dangerous. It sometimes includes
High Surge Voltage that could cause dangerous arcs of explosive short in
the instrum ent and could result in serious inj ury to the ope rator. For
dangerous volta ge measurement on High Power Line or High Volt age
Circuit, always keep the instrument away from your body without holding it in
your hands. Do not touch the Clamp Meter, its Test Leads, and any part of
the circuit.

Thank you for purchasing KAISE "MODEL SK-7820/7825 LEAKAGE CLAMP
METER". To obtain the maximum performance of this instrument, read this
Instruction Manual carefully, and take safe measurement.

Inspect the instrument and acessories for transport damage. If there is any
damage or missing items, ask your local dealer for replacement.
Confirm that the following items are contained in the package.

Children and the persons who do not have enough knowledge
about electric measurements must not use this instrument.
Do not measure the electricity naked or barefooted to protect
yourself from electrical shock hazard.
Be careful not to get hurt with the sharp test lead pins.
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.
Avoid the c lamp meter from hard mechan ical shock or
vibration, high temperature and strong magnetic field.
Remove the batteries when the clamp meter is out of use for a
long time. The exhausted batteries might leak electrolyte and
corrode the inside.
Do not measu re AC high-frequenc y current. Clamp h ead
becomes heated and could damage the instrument.

Always confirm that FUNCTION Switch is set to the correct position. Do not
measure voltage at   and   positions.

Detach test leads from measuring circuit before switching measurement functions
or removing battery cover for battery replacement.

WARNING 8. Safety Line

Do not put your fingers over the safety
line while current measurement.

To avoid measurement error due to the noise effects to the internal "auto-initialize
zero" circuit, turn the power on keeping the unit away from such equipments like
transformer or motor. For example, keep 1m or more from 100A conductors.
Measurement must be started after confirming "0" indication on LCD.

WARNING.

Unplug test leads from in put ter minals w hile cu rrent
measurement.

Clamp on conductor(s) in AC current measurement.

Correct knowledge of electric measurements is essential to avoid unexpected
danger such as operator's injury or damage to the instrument. Read carefully and
observe the following precautions for safety measurements.

Do not hold Clamp Meter and test leads in your hands. Keep safety distance
from power source or circuit to be measured not to touch the dangerous
voltage.
Attach black and red alligator clips to test lead pins.
Turn off the power of the circuit to be measured when connecting test leads.
After measurement, before detaching alligator clips (test leads), turn the circuit
power off and discharge the all capacitors.

Before measurement, confirm the body of this instrument and handle insulators of
the Test Lead have no cracks or any other damages. Dust, grease and moisture
must be removed.


High Power Line (High Energy Circuits) such as Distribution Transformers, Bus
Bars and Large Motors are very dangerous. High Power Line sometimes includes
High Surge Voltage that could cause explosive short in the instrument and could
result in shock hazard. For voltage measurement of High Power Line, do not touch
Clamp Meter, its Test Leads, and any part of the circuit.

Even for Low Energy Circuits of electric/electronic appliances, such as heating
elements, small motors, line cords and plugs, High Voltage Measurements are
very dangerous. Do not touch Clamp Meter, Test Leads, and any part of the
circuit. Generally, shock hazard could occur when the current between the circuit,
that involves more than 33V rms or 46.7V DC or peak, and ground goes up to

0.5mA or more.

For dangerous voltage measurement, strictly observe the warnings below.
