Introduction

Thank you for purchasing the HIOKI “Model 3174, 3174-01 AC Automatic Insula-

tion/Withstanding HiTester.” To obtain maximum performance from the instru-

ment, please read this manual first, and keep it handy for future reference.

• When you receive the instrument, inspect it carefully to ensure that no dam-

age occurred during shipping. In particular, check the accessories, panel

switches, and connectors. If damage is evident, or if it fails to operate accord-

ing to the specifications, contact your dealer or Hioki representative.

• When transporting the instrument, use the original packing materials in which

it was shipped, and pack in a double carton. Damage occurring during trans-

portation is not covered by warranty.

* The 3174-01 AC Automatic Insulation/Withstanding HiTester can be used with

GP-IB.

Safety Information

Safety Symbols 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.

The following symbols in this manual indicate the relative importance of cautions

and warnings.

Safety Information

This instrument is designed to comply with IEC 61010 Safety Standards,

and has been thoroughly tested for safety prior to shipment. However, mis-

handling during use could result in injury or death, as well as damage to

the instrument. Using this instrument in ways other than those specified in

this manual may damage functions which guarantees the safety of this

instrument. Be certain that you understand the instructions and precau-

tions in the manual before use. We disclaim any responsibility for acci-

dents or injuries not resulting directly from instrument defects.

In the manual, the symbol indicates particularly important informa-

tion that the user should read before using the instrument.

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.

Indicates that dangerous voltage may be present at this terminal.

Indicates DC (Direct Current).

Indicates AC (Alternating Current).

Indicates a grounding terminal.

Indicates a protective conductor terminal.

Indicates the ON side of the power switch.

Indicates the OFF side of the power switch.

Indicates that incorrect operation presents an extreme haz-

ard that could result in serious injury or death to the user.

Indicates that incorrect operation presents a significant

hazard that could result in serious injury or death to the

user.

Indicates that incorrect operation presents a possibility of

injury to the user or damage to the instrument.

Indicates advisory items related to performance or correct

operation of the instrument.

Safety Information

Other symbols

Accuracy We define measurement tolerances in terms of f.s. (full scale), rdg. (reading) and

dgt. (digit) values, with the following meanings:

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 least-significant digit.

Measurement categories (Overvoltage categories)

This instrument complies with CAT I, CAT II safety requirements.

To ensure safe operation of measurement instrument, 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 catego-

ries correspond to electri-

cal environments with

greater momentary

energy. So a measurement

instrument designed for

CAT III environments can

endure greater momen-

tary energy than a instru-

ment 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.

Never use a CAT I measuring instrument in CAT II, III, or IV environments.

The measurement categories comply with the Overvoltage Categories of the

IEC60664 Standards.

This symbol indicates that the product conforms to safety regulations

set out by the EC Directive.

Indicates a prohibited action.

(p. ) Indicates the location of reference information.

Indicates quick references for operation and remedies for trouble-

shooting.

*Indicates that descriptive information is provided below.

CAT I: Secondary electrical circuits connected to an AC electrical outlet

through a transformer or similar instrument.

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 dis-

tribution panel to outlets.

CAT IV: The circuit from the service drop to the service entrance, and to the

power meter and primary overcurrent protection instrument (distribu-

tion panel).

Operating Precautions

Operating temperature and humidity:

0 to 40°C at 80% RH or less (no condensation)

Temperature and humidity range for guaranteed accuracy:

23±5°C, 80%RH or less (no condensation)

after 10 minutes minimum warm-up

Installation • The instrument should be operated only with the bottom side downwards.

• Vents must not be obstructed.
