1. SAFETY WARNINGS
This clamp sensor has been designed and tested according to
IEC61010-1: Safety Requirements for Electronic Measuring A pparatus,
and delivered in the best condition after pa ssing quality c ontrol 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 throu gh
these operating instructions before using the clamp sensor.
# DANGER
● 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
necessary.
● The clamp sensor is to be used only in its intended applicat ions.
● Understand and follow all the safety instructions contained in
the manual.
It is essential that the above instruc tions are adhered to. Failure to
follow the above instructions may cause injury, clamp sensor
damage and/or damage to equipment und er test. K YORITS U is not
liable for any damage resulting from the users mishandli ng of the
clamp sensor.
The symbol # indicated on the c lamp sensor means that the user
must refer to the related par ts 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 fo r conditions and actions that are likely
to cause serious or fatal injury.
# WARNING: is reserved for conditions and actio ns that can
cause se rious or fatal injury.
# CAUTION: is reser ved for conditions and actions th at can
cause injury or instrument damage.
# DANGER
● With attention to the measurement c ategory to whi ch the object
under test belong s, and do not make measurements on a circuit
in which t he electrical potential exceeds the following valu es:
300V fo r CAT. IV and 600V for CAT. III or lower categories.
● Never attempt to make any measurement if any a bnormal
conditions, su ch as a broken cover or exposed metal par ts are
present on the clamp sensor.
● Do not disassemble, install substitute parts o r make any
modification to the clamp sensor. Return the c lamp sensor to
your local KYORITSU distributor for repair or re- calib ration i n
case of suspected faulty operation.
● Do not use the clamp sensor if the clamp senso r or your hands
are wet. Otherwise, electrical shock acci dent may oc cur.
● Use insulated protective gears for your safety w hen using this
clamp sensor.
Do not step o n or pinch the cord; it may damag e the jacket of cord.
●
●
Do not expo se the clamp sensor to direc t sunlight, high temperatures,
humidit y or dew. Otherwise, it may cause deformation or insulation
degradation and cannot meet the original specification.
● Not to give shocks, such as vibration o r drop, whi ch may
damage the clamp sensor, during transit or use.
● Use a damp cloth with water or neut ral detergent for c leanin g the
clamp sensor. Do not use abrasives or solvents.
● This clamp sensor is not designed to be dust or waterpro of. Do
not use it dusty places or where the cl amp 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, matc hing area of Jaws
may be damaged and cause influences on the measurements.
● Do n ot bend or p ull the ro ot of the cable in or der to prevent
breaks in t he cable.
● Never apply the current exceedi ng the measuring range for a
long time. It may damage the clamp sensor.
● Never co nnect /remove the connector s while connected devic es
are on or clamping o nto the conductor under test. Otherwi se, the
connected devices or clamp sens ors may be damaged.
● Ac curate measurement may not be obtained in the vicinit y of
strong magnetic f ields such as transformers, hi gh-current
circuits or wireless machines.
Meaning of symbols on the clamp sensor:
User must refer to the explanations in the instruction manual

# WARNING
# CAUTION
Measurement Category:
To ensure safe operation of measuring instr uments, IEC 61010
establishes safety standards for various electrical environments,
catego rized 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
one designed for CAT.II.
O : Circ uits whi ch are not directly conne cted to th e mains
power supply.
CAT.II : Electric al circ uits of equipment c onnec ted to an AC
electrical outlet by a power cord.
CAT.III : Pr imary electrical c ircuits of the equipment c onnec ted
direct ly to the distribution panel, and feeders from the
distribution panel to outlets.
CAT.IV : The circuit f rom the service drop to the service ent rance,
and to the power meter a nd primary over- current
protection device (distribution panel).

6-3 Connec ting w ith Logger (K EW5010/5020)
When using this c lamp sensor together wit h our KEW 5010 / 5020
Logger;
(1) Connect the clamp sensor to
CH1 of KEW5 010/ 5020 while
KEW5010 / 5020 is in powered
off status.
(2) Then power on KEW5010 /
5020. Time will be displayed,
and then
will be displayed. (K EW5010/
5020 checks the connected
clamp sensors when it is
powered o n, and detects and
displays t he clamp sensor t ype and a proper range
automatically.)
(3) Now the instrument is ready for
measurements. When
connection) is displayed on the
LCD; it means no clamp sensor is
connected to the selected channel
or the connection is loo se.
In this case, check the connecti on and rec onnec t the clamp
sensor,and power of f KEW5010 / 5020. Then power it o n again.
* Only KEW5010 / 5020 which have the following or later ser ial
