1. SAFETY WARNINGS
This instrument has been designed and tested according to IEC61010:
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.
The ref ore, read through these oper ating in struction s 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.
● 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 instru ctions may caus e injury, in strument damag e and/or
damage to equipment under test.
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
injury or instrument damage.
DANGER
● Never make measurement on a circuit in which the electrical potential
exceeds AC600V.
● Connect this instrument to the secondary side of a circuit breaker
because the secondary side is protected by a breaker at accidental
short-circuit. Do not make measurements at the primary side because
Current capacitance at the primary side is quite big and serious damage
may occur at accidental short-circuit.
WARNING
● Never attempt to make any measurement if any abnormal conditions,
such as a broken cover or exposed metal parts are present on the
instrument.
● Do not disassemble, install substitute parts or make any modification to
the instrument. Return the instrument to your local KYORITSU distributor
for repair or re-calibration in case of suspected faulty operation.
● Do not use the instrument if the instrument or your hands are wet.
Otherwise, electrical shock accident may occur.
● Us e ins ula t ed prot e cti ve gea rs for you r safe ty whe n usi ng thi s
instrument.
CAUTION
●Do not step on or pinch the cord; it may damage the jacket of cord.
● Do not expose the instrument to direct sunlight, high temperatures,
humidity or dew. Otherwise, it may cause deformation or insulation
degradation and cannot meet the original specification.
● Not to give shocks, such as vibration or drop, which may damage the
instrument, during transit or use.
● Use a damp cloth with neutral detergent for cleaning the instrument. Do
not use abrasives or solvents.
● This instrument isn't waterproofed. Do not use i t dusty places or
where the instrument is likely to be wet. It may cause troubles on the
instrument.
● Never pinch foreign matters or give vibrations at the jointed parts of this
instrument. Otherwise, matching area of Jaws may be damaged and
cause influences on the measurements.
● Do not bend or pull the root of the cable in order to prevent breaks in the
cable.
● Never apply the current exceeding measuring range for a long time. It
may damage this instrument.
● Never connect/remove the connectors while connected devices are
on or clamping onto the conductor under test. Otherwise, connected
devices or sensors may be damaged.
● Accurate measurement may not be obtained in the vicinity of strong
magnetic field such as transformers, high-current circuits or wireless
machines.

AC
◊ Measurement categories(Over-voltage categories)
To ensure safe operation of measuring instruments, IEC 61010 establishes
safety standards for various electrical environments, categorized as CAT.I
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 environments can endure greater
momentary energy than one designed for CAT.II.
CAT.I: Secondary electrical circuits connected to an AC electrical outlet
through a transformer or similar device.
CAT.II: Pri mary electrica l c ircui ts of eq uipment conn ected 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 circu it f ro m the ser vice drop to the servi ce e ntr anc e,
and to the power m et er and primary overcu rrent protection
device(distribution panel).
2. FEATURES
●This is a Clamp Sensor capable of measuring AC current up to 3000A.
● Flexible and light weight because of an air core coil used at the Sensor
part
●One BOX contains measuring circuit for 3-channel. (8129-03)

6. OPERATING INSTRUCTIONS
Note
● Jointed part of the Clamp sensor may be disconnected if excessive force
is applied to. Insert pins in the Joint-fixing-hole to ensure a firm connection.
(see the illustration below)
Use non-conductive pin for fixing the Joint in order to avoid getting an
electrical shock.
● Clamp onto one conductor only; measurements cannot be made when
clamping single-phase (2-wire) or three-phase (3-wire) at the same time.

6-3 Setting on MODEL6300 Power Meter
When using this instrument together with our Power meter, MODEL6300,
setting for the type of Clamp and available Current ranges on MODEL6300
are as follows.
(For the details of setting procedure, please refer to the instruction manual
for MOEL6300.)
Setting on MODEL6300

＊ Range of 300A at KEW8129 isn't available when using the sensor with
MODEL6300.
＊ MODEL6300 differs from KEW5010/5020 and doesn't recognize the type
of Sensor or ranges when it is powered on;
above setting is required for precise measurements.

(4) Clamp onto one conductor under the test. Locate the conductor at
the center of the Clamp sensor. When connecting the Sensor with
our Power meter (MODEL6300 etc.), check the direction of the Guide
arrow mark indicating the current flowing direction marked on the Joint
of the Clamp sensor to make the phase of the current under test and
output voltage synchronized.
(5) Confirm that the Joint on the Clamp sensor is firmly locked.
(6) Select any desirable range (300A/ 1000A/ 3000A) with the RANGE
Button. When powering off the instrument once and powering on again,
the range will be the one selected before powering off the instrument.
