FOR SAFETY MEASUREMENTS!!
To prevent an electrical shock hazard to the operator and/or damage to the
instruments, read this instruction manual carefully before using the
instrument. WARNINGS with the symbol
on the instrument 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)".
The symbol in this manual advises the user of an
WARNING 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.
WARNING
Measurement on High Power Line (High Energy Circuits) is very dangerous.
It sometimes includes High Surge Voltage that could cause dangerous arcs
of explosive short in the instrument and could result in serious injury to the
operator. When measuring high power line, be careful not touch any part
of the circuit.

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.
1. UNPACKING AND INSPECTIONS
Confirm if the following items are contained in the package in good condition.
If there is any damage or missing items, ask your local dealer for replacement.

3-1. WARNINGS
WARNING 1. Checks of the Instrument
Before measurement, check if there are no damage to the instrument. Dust,
grease and moisture must be removed.
WARNING 2. Warning for High Power Line Measurement
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. 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. When measuring high power line, do not touch the live line and
keep enough distance.
WARNING 3. Maximum Input Observance
Do not measure any current that might exceed the specified maximum input value.
3-2. PRECAUTION FOR USE
CAUTION : Do not measure AC high-frequency current. Clamp head
becomes heated and could damage the instrument.

4-4. Clamp Head
Clamp a single conductor in the center of clamp head.
NOTE : Measurement cannot be done if the several conductors are clamped.
4-5. Safety Line
The line to protect yourself against electrical shock hazard. Always keep your
fingers behind the safety line.
about electric measurements must not use this instrument.
Do not measure the electricity in naked of barefooted to
protect yourself from electrical shock hazard.
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.
Remove the battery when the instrument is out of use for a
long time. The exhausted battery might leak electrolyte and
corrode the inside.
4. NAME ILLUSTRATION
WARNING
To avoid electrical shock, detach the clamp meter from the circuit when to
replace the battery and turn it off.
Replace the battery when "BAT" lights up on LCD.
1. Turn off the clamp meter.
2. Loosen a screw of battery cover and remove it in the direction of an arrow.
3. Remove the exhausted battery. Insert a tweezers (or similar tool) into the side
hole of the battery case and push the battery up.
4. Insert a new 3V CR2032 battery in correct polarity, + mark up.
5. Fix the battery cover and tighten the screw.
NOTE : Remove the batteries when the instrument is out of use for a long time.
The exhausted batteries might leak electrolyte and corrode the inside.
NOTE : Installed battery is for inspection purpose and might be exhausted earlier
than the new battery.

Hole
One 3V CR2032 battery is installed in this instrument. When battery is exhausted,
"BAT" lights up on LCD. For the replacement, refer to "6-2. BATTERY REPLACEMENT".
LCD displays "OL" when the input value exceeds 400A AC.
WARNING
Do not measure any current that might exceed 300A AC (300V line maximum)
to avoid electrical shock hazard and/or damage to the instrument .
4. AUTO POWER OFF
Approx. 12 minutes after the last operation of the POWER or DH keys the clamp
meter will automatically turn off.
NOTE : There is small current consumption even in the auto power off or power
off conditions.
NOTE : Press POWER Key twice to turn on the clamp meter after the auto power off.
