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 standards for various electrical environments, catego-
rized as CAT II to CAT IV, and called measurement 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
8
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 contact your authorized Hioki
distributor or reseller for replacements.
Installation environment
Operating Precautions
Before Use
Instrument Installation
• This instrument is not drip-proof. Install the instrument with the
measurement cables hanging lower than the instrument to pre-
vent water or other fluid from entering the instrument through the
measurement cables and terminal block.
• The maximum operating (ambient) temperature for the LR8432-
20 is 40°C. Do not attempt to use in higher temperature environ-
ments.
• Correct measurement may be impossible in the presence of
strong magnetic fields, such as near transformers and high-cur-
rent conductors, or in the presence of strong electromagnetic
fields such as near radio transmitters.
• If liquid enters the enclosure through an air vent or other opening, it
may damage the instrument’s internal circuitry. Exercise caution con-
cerning the surrounding environment when installing the instrument.
Do not place the instrument on an unstable table or an inclined
place. Dropping or knocking down the instrument can cause injury
or damage to the instrument.

9
Installation Precautions
• If the instrument is used in any state other than the following, the
measurement accuracy may not satisfy the device specifications.
• Leave sufficient space around the ventilation holes and install the
instrument with the holes unobstructed.
• Avoid temperature changes around the terminal block. Especially
avoid directed airflow such as from an electric fan or air conditioner
vent. Thermocouple inputs are prone to measurement errors.
• When the instrument is moved to a location with significantly dif-
ferent ambient temperature, allow at least 30 minutes for thermal
equalization before measuring.
Horizontal placement Upright placement
Handling the Instrument
• Do not allow the instrument to get wet, and do not take mea-
surements with wet hands. This may cause an electric shock.
• Do not attempt to modify, disassemble or repair the instru-
ment; as fire, electric shock and injury could result.
To avoid damage to the instrument, protect it from physical shock
when transporting and handling. Be especially careful to avoid
physical shock from dropping.
This instrument may cause interference if used in residential
areas. Such use must be avoided unless the user takes special
measures to reduce electromagnetic emissions to prevent interfer-
ence to the reception of radio and television broadcasts.

Operating Precautions
10
Handling the Cords and Cables
The cable is hardened under the 0°C or colder environment. Do
not bend or pull it to avoid tearing its shield or cutting cable.
Before Turning Power On
Using the Battery Pack
• For battery operation, use only the HIOKI Model 9780 Battery
Pack. We do not take any responsibility for accidents or
damage related to the use of any other batteries.
Refer to “2.1 Using the Battery Pack (Option)” (p. 28).
Using the AC Adapter
• Use only the supplied Model Z1005 AC Adapter. AC adapter
input voltage range is 100 V to 240 VAC at 50 Hz/60 Hz. To
avoid electrical hazards and damage to the instrument, do
not apply voltage outside of this range.
• Turn the instrument off before connecting the AC adapter to
the instrument and to AC power.
• To avoid electrical accidents and to maintain the safety spec-
ifications of this instrument, connect the power cord pro-
vided only to a 3-contact (two-conductor + ground) outlet.
• Use only the designated power cord with this instrument.
Use of other power cords may cause fire.
• Before turning the instrument on, make sure the supply volt-
age matches that indicated on its power connector. Connec-
tion to an improper supply voltage may damage the
instrument and present an electrical hazard.
• Do not connect the supply voltage improperly. Doing so may
damage the instrument’s internal circuitry.
• Avoid using an uninterruptible power supply (UPS) or DC/AC
inverter with rectangular wave or pseudo-sine-wave output to
power the instrument. Doing so may damage the instrument.
• When the power is turned off, do not apply voltage or current to
the terminals. Doing so may damage the instrument.

Operating Precautions
11
• After use, always turn OFF the power.
• Brief power interruptions of 40 ms or less will not cause this
instrument to malfunction. However, Longer interruptions may
cause the instrument to shut itself off, so consider local power
conditions before installing, as appropriate.
• To ensure that recording is not interrupted by power outages, you
can use the Z1005 AC Adapter and 9780 Battery Pack together.
About Inputs and Measurement
• Do not use the instrument with circuits that exceed its rat-
ings or specifications. Doing so may cause it to become
hot, resulting in bodily injury.
• To avoid electrical hazards and damage to the instrument,
do not apply voltage exceeding the rated maximum to the
input terminals.
• The maximum input voltage (and the maximum rated volt-
age to earth) for the analog input terminals is 30 V AC rms
(or 60 V DC). If these limits are exceeded, the instrument
may be damaged and personal injury or death could occur,
so do not attempt measurement.
• Do not leave the instrument connected to test objects in envi-
ronments where a voltage surge might exceed the dielectric
withstand voltage. Doing so could result in damage to the
instrument, bodily injury or fatal accident.
• Channels are insulated by semiconductor relays. When a
voltage beyond the specification is applied between the
channels, the semiconductor relay may short circuit. Please
ensure that a voltage beyond specification, especially a
surge such as a lightning, is never applied. When an abnor-
mal measurement value is observed, please contact your
authorized Hioki distributor or reseller for inspection.
IMPORTANT
Select Hioki 9641 Connection Cable for use as a cable for the
pulse input connector.
The waveform for an open channel may sometimes appear to be
influenced by the signals of the other channels being measured. If
you do not like this, please set the waveform display of the open
channel to OFF or short-circuit the input terminals of the open
channel by connecting the positive and negative terminal.
