Introduction

Thank you for purchasing this HIOKI "3286

CLAMP ON POWER HiTESTER." To get the

maximum performance from the product, please read

this manual first, and keep this at hand.

Importance

This product is the clamp on power meter which

keeps measurement function of the multiple

functions. If you set up a function mode in

advance, the mode will start up from the next use.

Have it set up for the preferable use. (Refer to "2.10

Measurement Condition Save Function)

Request

We have tried to bring this manual as close to

perfection as we could achieve. If perchance you

find any unclear portions, mistakes, omissions, or

the like, we would be most obliged if you could

please notify us of them via any HIOKI agent, or

directly.

Shipping Check

When you receive the product, inspect it carefully to

ensure that no damage occurred during shipping. In

particular, check the accessories, panel switches, and

connectors.

If damage is evident, or if it fails to operate

according to the specifications, contact your dealer

or HIOKI representative.

Safety

DANGER

This equipment is designed according to IEC

61010 Safety Standards, and has been tested for

safety prior to shipment. Incorrect measurement

procedures could result in injury or death, as

well as damage to the equipment. Please read

this manual carefully and be sure that you

understand its contents before using the

equipment. The manufacturer disclaims all

responsibility for any accident or injury except

that resulting due to defect in its product.

Safety

This manual contains information and warnings

essential for safe operation of the product and for

maintaining it in safe operating condition. Before

using the product, be sure to carefully read the

following safety notes.

Safety

DANGER

Indicates that incorrect operation

presents extreme danger of accident

resulting in death or serious injury to the

user.

WARNING

Indicates that incorrect operation

presents significant danger of accident

resulting in death or serious injury to the

user.

CAUTION Indicates that incorrect operation

presents possibility of injury to the user

or damage to the equipment.

NOTE Denotes items of advice related to

performance of the equipment or to its

correct operation.

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 device which is double-

insulated.

The following symbols in this manual indicate the

relative importance of cautions and warnings.

Safety Symbols

Safety

We define measurement tolerances in terms of rdg.

(reading) and dgt. (digit) values, with the following

meanings:

rdg. (reading or displayed value)

The value currently being measured and indicated

on the measuring product.

dgt. (resolution)

The smallest displayable unit on a digital measuring

product, i.e., the input value that causes the digital

display to show a "1".

Overvoltage Categories

To ensure safe use of measurement, IEC 60664

establishes safety level standards for different

locations, classified as CAT I through CAT IV, and

called overvoltage categories. These are defined as

follows.

CAT I: Secondary electrical circuits that are

connected to a wall outlet through a

transformer or similar device.

CAT II: Primary electrical circuits in equipment

connected to a wall outlet via 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 between the distribution panel and

outlets.

CAT IV: The circuit from the service drop to the

service entrance, then to the power meter

and to the primary overcurrent protection

device.

Safety

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. Use of a lower

category product in a higher category environment

could result in a severe accident and must be

carefully avoided.

vii

Attentions During Use

DANGER

To avoid short circuits and potentially life-

threatening hazards, never attach the clamp to a

circuit that operates at more than the maximum

rated voltage / 600V, or over bare conductors.

Clamp-on probe 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.

WARNING

To avoid electric shock, do not allow the

product to get wet, and do not use it when your

hands are wet.

To avoid electric shock when measuring live

lines, wear appropriate protective gear, such as

insulated rubber gloves, boots and a safety

helmet.

Attentions During Use

Follow these precautions to ensure safe operation

and to obtain the full benefits of the various

functions.
