1. Safety warnings
○ This instrument has been designed, manufactured and
tested according to IEC 61010: Safety requirements
the best condition after passing quality control tests.
This instruction manual contains warnings and safety
safe operation of the instrument and to maintain it in
instructions before using the instrument.
# WARNING
● Read through and understand instructions contained
in this manual before using the instrument.
● Keep the manual at hand to enable quick reference
whenever necessary.
● The instrument is to be used only in its intended
applications.
　 The operating instructions described in the manual
must be observed.
● Understand and follow all the safety instructions
contained in the manual. It is essential that the
above instructions are adhered to. Failure to follow
the above instructions may cause injury and or
instrument damage.
Kyoritsu is by no means liable for any damage
resulting from the instrument in contradiction to this
cautionary note.
○ The symbol indicated on the instrument, means that #

# DANGER　 is reserved for conditions and actions
that are likely to cause serious or
fatal injury.
# 　 is reserved for conditions and actions WARNING
that can cause serious or fatal Injury.
# CAUTION　 is reserved for conditions and actions
that can cause minor injury or
instrument damage.
# DANGER
● Never make measurement on a circuit in which the
electrical potential exceeds AC300V.
● Do not make measurement when thunder rumbling. If
the instrument is in use, stop the measurement
immediately and remove the instrument from the
measured object.
● Do not attempt to make measurement in the
presence of flammable gasses. Otherwise, the use
of the instrument may cause sparking, which can
lead to an explosion.
● The transformer jaws are made of metal and their
tips are not completely insulated. Be especially
careful about the possible shorting where the
measured object has exposed metal parts.
● Never attempt to use the instrument if it's surface or
your hand are wet.
● Do not exceed the maximum allowable input of any
measuring range.
● Use insulated protective gears, such as insulated
gloves, for your safety when possible electric shock
hazards are concerned.
● Keep your fingers and hands behind the barrier
during a measurement.
# WARNING
● Never attempt to make any measurement, if any
abnormal conditions are noted, such as broken
case, and exposed metal parts.
● Do not install substitute parts or make any
modification to the instrument. Return the
instrument to the distributor from who you
purchased this instrument for repair or re-calibration
in case of suspected faulty operation.
● Always keep your fingers and hands behind the
barrier on the instrument to avoid the possible
shock hazard.
# CAUTION
● Do not step on or pinch the cord to prevent the
jacket of cable from being damaged.
● The output connector shall be removed or
connected without clamping a conductor.
Otherwise, it may cause a failure.
● Do not expose the instrument to direct sunlight,
high temperatures, humidity or dew.
● Never give shocks, such as vibration or drop, which
may damage the instrument.
● Use a damp cloth and detergent for cleaning the
instrument. Do not use abrasives or solvents.

○Measurement categories(Over-voltage categories)
To ensure safe operation of measuring instruments, IEC
61010 establishes safety standards for various electrical
environments, categorized as o to CAT IV, and called
measurement categories. Higher-numbered categories
correspond to electrical environments with greater
momentary energy. So a measuring instrument designed for
CAT III enviroments can endure greater momentary energy
than one desined for CAT II.
　O(None, Other): Circuits which are not directly
connected to the mains power supply.
　CAT Ⅱ: Primary electrical circuits of equipment
connected to an AC electrical outlet by a
power cord.
　CAT Ⅲ: Primary electrical circuits of the equipment
connected directly to the distribution panel,
and feeders from the distribution panel to
outlets.
　CAT Ⅳ: The circuit from the service drop to the
service entrance, and to the power meter and
primary overcurrent protection device
(distribution panel).
O: Device which is
not directly
connected to the
mains power supply

6. Operating instructions
# DANGER
● Never make measurement on a circuit in which the
electrical potential exceeds AC300V in order to avoid
possible shock hazard.
● The transformer jaws are made of metal and their tips
are not completely insulated. Be especially careful
about the possible shorting where the measured object
has exposed metal parts.
# CAUTION
● Take sufficient care to avoid shock, vibration or
excessive force when handling the instrument.
Otherwise, precisely adjusted transformer jaws
will be damaged.
● When transformer jaws do not fully close, never try
to close them by force, but make them free to move
and try again. If a foreign substance is stuck in
the jaw tips, remove it.
● When making current measurements, keep the
transformer jaws fully closed.
　 Otherwise, accurate measurements cannot be
taken. Maximum conductor size is 24mm in
diameter.
● Hold the inserting part (except for the cable) and
disconnect the Output connector from the
measuring instrument so as not to cause a break in
the cable.
6-1 Measurement procedures
(1) Connect the Output connector to the Input terminal of
the measuring instrument.
(2) Press the Trigger to open the transformer jaws and
clamp onto one conductor. In this case, the measured
conductor shall be at the center of the jaws.
When connecting a sensor with a Power meter (our
Power meter, MODEL6300, etc.) match the arrow
mark (Power source to load), which is indicated on
the transformer jaws, with the current flowing
direction in 0order to synchronize the phases of
measured current and output voltage.
(3) Ensure that the tips of transformer jaws are firmly
closed.
