__________________________________________________
_____________________________________________
The symbol printed on the product
indicates that the user should refer to a
corresponding topic in the manual (marked
with the symbol) before using the
relevant function.
In the manual, the symbol indicates
particularly important information that the
user should read before using the product.
Indicates AC (Alternating Current).
Indicates DC (Direct Current).
Indicates a double-insulated device.
Wear appropriate protective insulation
(insulating rubber gloves and boots, helmet
and etc.) when connecting and disconnecting
from live electric circuits.
DANGER
Indicates that incorrect operation presents an
extreme hazard that could result in serious
injury or death to the user.
WARNING
Indicates that incorrect operation presents a
significant hazard that could result in serious
injury or death to the user.
CAUTION Indicates that incorrect operation presents a
possibility of injury to the user or damage to
the product.
NOTE Advisory items related to performance or
correct operation of the product.
Safety symbols
The following symbols in this manual indicate
the relative importance of cautions and
warnings.

_____________________________________________
CAT I Secondary electrical circuits connected to an AC
electrical outlet through a transformer or similar
device.
CAT II Primary electrical circuits in equipment connected to
an AC electrical outlet by a power cord (portable tools,
household appliances, etc.)
CAT III Primary electrical circuits of heavy equipment (fixed
installations) 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).
Measurement categories
(Overvoltage categories)
This product complies with CAT III safety
requirements.
To ensure safe operation of measurement
product, IEC 61010 establishes safety
standards for various electrical environments,
categorized as CAT I to CAT IV, and called
measurement categories. These are defined as
follows.
Higher-numbered categories correspond to
electrical environments with greater momentary
energy. So a measurement device designed for
CAT III environments can endure greater
momentary energy than a device designed for
CAT II.
Using a measurement product in an
environment designated with a higher-numbered
category than that for which the product is rated
could result in a severe accident, and must be
carefully avoided.
Never use a CAT I measuring product in CAT
II, III, or IV environments.
The measurement categories comply with the
Overvoltage Categories of the IEC60664
Standards.

DANGER
Before using the product the first time, verify
that it operates normally to ensure that the no
damage occurred during storage or shipping. If
you find any damage, contact your dealer or
Hioki representative.
When conductors being measured carry in
excess of the safe voltage level (SELV-E) and
not more than 300 V, to prevent short circuits
and electric shock while the clamp sensor jaw
is open, make sure that conductors to be
measured are insulated with material
conforming to (1) Overvoltage CategoryⅢ,(2)
Pollution Degree 2, and (3) Basic Insulation
Requirements for Working Voltages of 300 V.
Refer to the following standards regarding the
meanings of underlined terms.
IEC61010-1
IEC61010-2-031
IEC61010-2-032
Notes on Use
Follow these precautions to ensure safe
operation and to obtain the full benefits of the
various functions.

DANGER
Do not use clamp testers on bare conductors.
When the clamp sensor jaw is open, there is a
risk of short-circuits and accidents that could
result in injury or death.
Use clamp testers only on power lines up to AC
300 V rms, to avoid short-circuits and accidents
that could result in injury or death.
This product should only be connected to the
secondary side of a breaker, so the breaker can
prevent an accident if a short circuit occurs.
Connections should never be made to the
primary side of a breaker, because unrestricted
current flow could cause a serious accident if a
short circuit occurs.
Use only the specified Model 9445-02 (SA10-
0910N, SINO-AMERICAN) or 9445-03 (for EU)
(SA10-0910G, SINO-AMERICAN). AC adapter
input voltage range is 100 to 240 V AC (with
10% stability) at 50/60 Hz. To avoid electrical
hazards and damage to the product, do not
apply voltage outside of this range.
