Procedure

Operation and Screen Types

(p.15) Describes the screen types and an overview of the

operating keys.

Measurement Procedure

(p.19) Describes procedures from measurement prepara-

tion to analysis.

Monitoring Voltage Fluctua-

tions (p.22)

This section describes voltage measurement using

an AC transducer to acquire voltage fluctuation data

for one week, with the data automatically saved on a

CF card.

(The example transducer provides 0 V - 10 V DC

output proportional to 0 V - 150 V AC rms input.)

Monitoring Temperature

This section describes temperature measurement

using a type K thermocouple to acquire temperature

data once per second, for monitoring temperature

changes. The post-measurement saving method is

also described.

Monitoring Energy Con-

sumption (p.27)

This section describes pulse measurement using a

watt-hour meter* to acquire integrated power con-

sumption data for one month.

* The example watt-hour meter provides an output of

50,000 pulses/kWh.

Monitoring Heat Flow (Model

LR8432-20 only) (p.29)

This section describes heat flow and temperature

measurement using the Heat Flow Sensor and ther-

mocouples. (LR8432-20 only)

Here we explain how to measure heat flow and tem-

perature every second (using the Heat Flow Sensor

and thermocouples K) and how to measure changes

in these variables.

Analysis (p.33) View and calculate waveform measurement values

using the A/B cursors.

Safety Information

This instrument is designed to conform to IEC 61010 Safety Standards,

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

using the instrument in a way not described in this manual may negate

the provided safety features.

Before using the instrument, be certain to carefully read the following

safety notes:

Safety Information

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.

With regard to the electricity supply, there are risks of electric

shock, heat generation, fire, and arc flash due to short cir-

cuits. If persons unfamiliar with electricity measuring instru-

ment are to use the instrument, another person familiar with

such instruments must supervise operations.

Safety Symbols

Indicates cautions and hazards. When the symbol is printed on the instrument,

refer to a corresponding topic in the Instruction Manual.

Indicates DC (Direct Current).

Indicates AC (Alternating Current).

Indicates the ON side of the power switch.

Indicates the OFF side of the power switch.

Safety Information

Notation

In this document, the risk seriousness and the hazard levels are classified as fol-

lows.

Indicates an imminently hazardous situation that will result in death or seri-

ous injury to the operator.

Indicates a potentially hazardous situation that may result in death or seri-

ous injury to the operator.

Indicates a potentially hazardous situation that may result in minor or mod-

erate injury to the operator or damage to the instrument or malfunction.

Indicates information related to the operation of the instrument or mainte-

nance tasks with which the operators must be fully familiar.

IMPORTANT

Safety Information

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 cur-

rently selected range.

Example: For the 1 V range, f.s. = 1 V

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

To ensure safe operation of measurement instruments, IEC 61010 establishes safety stan-

dards for various electrical environments, categorized as CAT II to CAT IV, and called mea-

surement categories.

• Using a measuring instrument in an environment desig-

nated 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 measuring instrument that lacks category label-

ing in a CAT II to CAT IV measurement environment. Doing

so could result in a serious accident.

CAT II:

When directly measuring the electrical outlet receptacles of the primary elec-

trical circuits in equipment connected to an AC electrical outlet by a power

cord (portable tools, household appliances, etc.)

CAT III:

When measuring the primary electrical circuits of heavy equipment (fixed

installations) connected directly to the distribution panel, and feeders from

the distribution panel to outlets

CAT IV:

When measuring the circuit from the service drop to the service entrance,

and to the power meter and primary overcurrent protection device (distribu-

tion panel)

Safety Information

Difference between “Measurement” and “Recording”

The measurement and recording processes are distinguished as follows for the purposes of

these instructions.

Measured data (data acquired in internal memory) is erased whenever a new measurement

starts. To retain data, always record (save) it.

Measurement: The acquisition of input values into the instrument’s internal memory or to

a PC via communications.

Recording: Storing measurement data on a CF card, USB flash drive or on a PC via

data communication.

Operating Precautions

Follow these precautions to ensure safe operation and to obtain the full benefits of

the various functions.

• Before using the instrument for the first time, verify that it operates normally to

ensure that no damage occurred during storage or shipping. If you find any dam-

age, contact your authorized Hioki distributor or reseller.

• Before using the instrument, make sure that the insulation on the cables is undam-

aged and that no bare conductors are improperly exposed. Using the instrument in

such conditions could cause an electric shock, so your authorized Hioki distributor

or reseller for replacements.

Installation environment

Operating Precautions

Before Use

Instrument Installation

Installing the instrument in inappropriate locations may

cause a malfunction of instrument or may give rise to an acci-

dent. Avoid the following locations:

• Exposed to direct sunlight or high temperature

• Exposed to corrosive or combustible gases

• Exposed to a strong electromagnetic field or electrostatic

charge

• Near induction heating systems (such as high-frequency

induction heating systems and IH cooking equipment)

• Susceptible to vibration

• Exposed to water, oil, chemicals, or solvents

• Exposed to high humidity or condensation

• Exposed to high quantities of dust particles

• This instrument is not drip-proof. Install the instrument with the mea-

surement cables hanging lower than the instrument to prevent water

or other fluid from entering the instrument through the measurement

cables and terminal block.

• The maximum operating (ambient) temperature for the instrument is

40°C. Do not attempt to use in higher temperature environments.
