1. Safety warnings
○ This instrument has been designed, manufactured and
tested according to IEC 61010: Safety requirements for
Electronic Measuring apparatus, and delivered in the
best condition after passing quality control tests. This
instruction manual contains warnings and safety rules
which have to be observed by the user to ensure safe
operation of the instrument and to maintain it in safe
condition. Therefore, read through these operating
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.
○ The symbol indicated on the instrument, means that
the user must refer to the related parts in the manual for
safe operation of the instrument. It is essential to read
the instructions wherever the
symbol appears in the
manual.
DANGER is reserved for conditions and actions
that are likely to cause serious or fatal
injury.
WARNING is reserved for conditions and actions
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.
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.

Safety symbols
○ Measurement categories(Over-voltage categories)
To ensure safe operation of measuring instruments, IEC
61010 establishes safety standards for various electrical
environments, categorized as CATⅠto CATⅣ, and
called measurement categories.
Higher-numbered categories correspond to electrical
environments with greater momentary energy, so a
measuring instrument designed for CATⅢ environments
can endure greater momentary energy than one
designed for CATⅡ.
CAT.Ⅰ: Secondary electrical circuits connected to an AC
electrical outlet through a transformer or similar
device.
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).

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.
