4. PIN ASSIGNMENT FOR OUTPUT TERMINAL
The pin assignment for the output terminal of this clamp sensor is as
* Pin assignment at the connecting terminal of measuring instrument
is symmetrical to above figure.
● Output signal passes between 3 and 5 of Output terminal.
● This clamp sensor is supplied power via an Output cable. Power
supply of +3.0 to +5.5V is required between 1 and 3 of Output
terminal and -3.0 to -5.5V is required between 2 and 3 of Output
● Never attempt to make any measurement if any abnormal
conditions, such as a broken cover or exposed metal parts are
present on the clamp sensor.
● Do not disassemble, install substitute par ts or make any
modification to the clamp sensor. Return the clamp sensor to
your local KYORITSU distributor for repair or re-calibration in
case of suspected faulty operation.
● Do not use the clamp sensor if the clamp sensor or your hands
are wet. Otherwise, electrical shock accident may occur.
● Use insulated protective gears for your safety when using this
Do not step on or pinch the cord; it may damage the jacket of cord.
Do not expose the clamp sensor 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 clamp sensor, during transit or use.
● Use a damp cloth with water or neutral detergent for cleaning the
clamp sensor. Do not use abrasives or solvents.
● This clamp sensor is not designed to be dust or waterproof. Do
not use it dusty places or where the clamp sensor is likely to be
wet. It may cause troubles on the clamp sensor.
● Never pinch foreign matters or give vibrations at the jointed
parts of this clamp sensor. 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
● Never apply the current exceeding the measuring range for a
long time. It may damage the clamp sensor.
● Never connect/remove the connectors while connected devices
are on or clamping onto the conductor under test. Otherwise, the
connected devices or clamp sensors may be damaged.
● Accurate measurement may not be obtained in the vicinity of
strong magnetic fields such as transformers, high-current
circuits or wireless machines.

Cautions for using this clamp sensor with KEW5010/5020:
Some KEW5010/5020 that were manufactured before the specific
timing of production may not be used with this clamp sensor. Please
refer to 6-3 Connecting with Logger (KEW5010/5020) and
This clamp sensor has been designed and tested according to
IEC61010-1: 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 clamp
sensor and to maintain it in safe condition. Therefore, read through
these operating instructions before using the clamp sensor.
● Read through and understand instructions contained in this
manual before starting to use the clamp sensor.
● Keep the manual at hand to enable quick reference whenever
● The clamp sensor is to be used only in its intended applications.
● Understand and follow all the safety instructions contained in
It is essential that the above instructions are adhered to. Failure to
follow the above instructions may cause injury, clamp sensor
damage and/or damage to equipment under test. KYORITSU is not
liable for any damage resulting from the users mishandling of the
The symbol # indicated on the clamp sensor means that the user
must refer to the related parts in the manual for safe operation of the
clamp sensor. 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.
● With attention to the measurement category to which the object
under test belongs, and do not make measurements on a circuit
in which the electrical potential exceeds the following values:
300V for CAT IV and 600V for CAT III or lower 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 environments can endure greater momentary energy than
O : Circuits which are not directly connected to the mains
CAT II : 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 t o th e po wer mete r and primar y over-c urrent
protection device (distribution panel).
