Introduction

Inspection

Thank you for purchasing the HIOKI

"Model 3403,3404 TACHO HiTESTER".

To obtain maximum performance from

the instrument, please read this manual

first, and keep it handy for future

reference.

When you receive the instrument,

inspect it carefully to ensure that no

damage occurred during shipping. If

damage is evident, or if it fails to operate

according to the specifications, contact

your dealer or Hioki representative.

____________________________________________

DANGER

This instrument is designed to comply

with 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 instrument

defects.

・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.

Safety Notes

This manual contains information and

warnings essential for safe operation of

the instrument and for maintaining it in

safe operating condition. Before using it,

be sure to carefully read the following

safety precautions.

Safety symbols

____________________________________________

DANGER Indicates that incorrect operation

presents an extreme hazard that

could result in serious injury or death

to the user.

ARNING 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.

The following symbols in this manual

indicate the relative importance of

cautions and warnings.

Overvoltage Categories

This instrument complies with CAT I

safety requirements.

To ensure safe operation of

measurement instruments, IEC 60664

establishes safety standards for various

electrical environments, categorized as

CAT I to CAT IV, and called overvoltage

categories. These are defined as follows.

____________________________________________

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).

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 instrument in an

environment designated with a higher-

numbered category than that for which

the instrument is rated could result in a

severe accident, and must be carefully

avoided.

____________________________________________

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

The maximum displayable value or scale

length. This is usually the name of the

currently selected range.

rdg. (reading or displayed value)

The value currently being measured and

indicated on the measuring instrument.

dgt. (resolution)

The smallest displayable unit on a digital

measuring instrument, i.e., the input value

that causes the digital display to show a

"1" as the leastsignificant digit.

Accuracy

We define measurement tolerances in

terms of f.s. (full scale), rdg. (reading)

and dgt. (digit) values, with the following

meanings:

____________________________________________

DANGER

To avoid damage to the instruments and

potentially life-threatening hazards,

observe the following precautions:

Be careful when measuring with the

contact adapter because rotation and

vibration of the instrument can produce

erratic results with either high or low

rotation speeds. Hold the main body

firmly against the rotator. Do not place

the instrument on a tripod when making

measurements.

If the contact tip is not fully inserted over

the contact adapter shaft, it could fall off

the shaft by touching the rotator. Make

sure the contact tip is firmly inserted over

the adapter shaft before making

measurements.

Notes on Use

Follow these precautions to ensure safe

operation and to obtain the full benefits

of the various functions.
