1. SAFETY WARNINGS

This clamp sensor has been designed and tested according to
IEC61010-1: Safety Requirements for Electronic Mea suring A pparatus,
and delivered in the best condition after passing 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 applications.

● Understand and follow all the safety instructions contained in

the manual.
It is esse ntial 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 users mishandling of the
clamp sensor.

The symbo l # 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 actions that can

cause se rious or fatal injury.

# CAUTION: is reser ved for conditions and actions that 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 values:
300V fo r CAT. IV and 600V for CAT. III or lower categories.

● Never attempt to make any measurement if any abnormal

conditions, such as a broken cover or exposed metal par ts are
present on the clamp sensor.

● Do not disass emble, install substitute parts o r make any

modif ication to the clamp sensor. Return the c lamp sensor to
your local KYORITSU distributor for repai r or re- calibration in
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 neutral deter gent for c leaning 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 mat ters or give vibrations at the jointed

parts of this clamp senso r. Otherwise, matching are a of Jaws
may be damaged and cause influences on the measurements.

● Do n ot bend or pull the ro ot of the cable in order to preve nt

breaks in t he cable.

● Never apply the current exceeding the measuring r ange for a

long time. It may damage the clamp sensor.

● Never co nnect /remove the connector s while connected devices

are on or clamping o nto the co nducto r under test. Otherwise, the
connected devices or clamp sensors may be damaged.

● Ac curate measurement may not b e obtain ed 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:

# WARNING

# CAUTION

Measurement Category:

To ensure safe operation of measuring instruments, IEC 61010
establishes safety standards for various electrical environments,
catego rized as O to CAT.IV, and called measurement c ategories.
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 connected to the 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 distribu tion 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).

displays t he clamp sensor t ype and a proper range
automatically.)

(3) Now the instrument is ready for

measurements. When 
