Inspection

______________________________________________________________

NOTE Testing monitor batteries installed in the unit may possibly be

weak. Replace batteries before extended measurement usage.

Before using the product, make sure that the insulation on the

sensor cables is undamaged and that no bare conductors are

improperly exposed. Using the product in such conditions could

cause an electric shock, so contact your dealer or Hioki

representative for repair.

Introduction

Ins

Safety Notes

______________________________________________________________

DANGE

This instrument is designed to conform to IEC 61010

Safety Standards, and has been thoroughly tested for

safety prior to shipment. However, mishandling

during use could result in injury or death, as well as

damage to the instrument. Be certain that you

understand the instructions and precautions in the

manual before use. We disclaim any responsibility for

accidents or injuries not resulting directly from

product defects.

Safety Symbols

The symbol printed on the instrument 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 instrument.

Indicates DC (Direct Current).

Notes

This manual contains information and warnings essential

for safe operation of the instrument and for maintaining it

in safe operating condition. Before using the instrument,

be sure to carefully read the following safety notes.

Safety Notes

______________________________________________________________

DANGE

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

instrument.

NOTE Advisory items related to performance or correct

operation of the instrument.

f.s. (maximum display or scale value, or length of scale)

Signifies the maximum display (scale) value or the length

of the scale (in cases where the scale consists of unequal

increments or where the maximum value cannot be

defined).

In general, this is the range value (the value written on

the range selector or equivalent) currently in use.

rdg. (displayed or indicated value)

This signifies the value actually being measured, i.e., the

value that is currently indicated or displayed by the

measuring instrument.

dgt. (resolution)

Signifies the smallest display unit on a digital measuring

instrument, i.e., the value displayed when the last digit on

the digital display is "1".

The following symbols in this manual indicate the relative

importance of cautions and warnings.

Accuracy

The specifications in this manual include figures for

"measurement accuracy" when referring to digital

measuring instruments, and for "measurement tolerance"

when referring to analog instruments.

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)

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.

Notes on Use

______________________________________________________________

DANGE

This product cannot be used on following voltage lines.

If the voltage exceeds, there will be a short-circuit

accident or electrocution accident will result.

CAT III, AC300 Vrms for 9657

CAT III, AC150 Vrms for 9658

To avoid short circuits and potentially life-threatening

hazards, never attach the clamp-on leak sensor to a

circuit that operates at more than the following

maximum rated voltage to earth.

AC300 Vrms for 9657

AC150 Vrms for 9658

Clamp-on leak sensor 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.

For model 9657

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 core jaw is open, make sure that conductors to

be measured are insulated with material conforming to

(1) Measurement Category III, (2) Pollution Degree 2,

and (3) Basic Insulation Requirements for Working

Voltages of 300 V.

Notes on Use

Follow these precautions to ensure safe operation and to

obtain the full benefits of the various functions.

Notes on Use

______________________________________________________________

DANGE

For model 9658

When conductors being measured carry in excess of

the safe voltage level (SELV-E) and not more than 150

V, to prevent short circuits and electric shock while the

clamp core jaw is open, make sure that conductors to

be measured are insulated with material conforming to

(1) Measurement Category III, (2) Pollution Degree 2,

and (3) Basic Insulation Requirements for Working

Voltages of 150 V.

Refer to the following standards regarding the

meanings of underlined terms.

IEC61010-1

IEC61010-2-031

IEC61010-2-032

WARNING

To avoid electric shock, do not allow the product to

get wet, and do not use it when your hands are wet.

When measuring the ground conductor on a

transformer Class 2 connection site, be careful not to

approach high voltage devices or conductors. Also, if

close to high voltage charging devices or if

measurement is otherwise difficult, first change the

route of the grounding wire.

To avoid damage to the product, protect it from

vibration or shock during transport and handling, and

be especially careful to avoid dropping.

This is a precision instrument: do not clamp any

foreign objects in the end of the clamp core, or insert

anything in the core gap.

Do not exert excessive pressure on the clamp sensor

or attempt to wedge the sensor into a tight spot for

measurement.
