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 currently 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 categ o ries
To ensure safe operation of measurement instruments, IEC 61010
establishes safety standards for various electrical environments, categorized as CAT II to CAT IV, and called measurement categories.

Operating Precautions
Operating Precautions
Follow these precautions to ensure safe operation and to obtain the full benefits of
the various functions.
Before Use
• Before using the instrument for the first time, verify that it operates normal
ensure that no damage occurred during storage or shipping. If you find any damage, contact your authorized Hioki distributor or reseller.
• Before using the instrument, make sure that the insulation on the cables is undamaged and that no bare conductors are improperly exposed. Using the instrument in
such c
onditions could cause an electric shock, so contact your authorized Hioki
distributor or reseller for replacements.

Instrument Installation
Installation environment
• This instrument is not drip-proof. Install the instrument with the
measurement 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 LR843220 is 40°C. D
ments.
• Correct measurement may be impossible in the presence of
strong magnetic fields, such as near transformers and high-current conductors, or in the presence of strong electromagneti
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 concerning the surrounding environment when installing the instrument.
o not attempt to use in higher temperature environ-
c
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.
Installation Precautions
Horizontal placement Upright placement
• 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 di
vent. Thermocoup le inp ut s are pr one to me asure ment error s.
• When the instrument is moved to a location with significantly different ambient temperature, allow at least 30 minutes for thermal
equalization be

Operating Precautions
fore measuring.
• Do not allow the in strum ent to g et we t, and do no t take measurements with wet hands. This may cause an electric shock.
• Do not attempt to modify, disassemble or repair the instrument; 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
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 dam age to the instrument, do
not apply voltage outside of this range.

instrument and present an electr ical hazard.
ent and to AC power.
r power cords may cause fire.
• 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.
• After use, always turn OFF the power.
IMPORTANT
Select Hioki 9641 Connection Cable for use as a cable for the
pulse input connector.
• 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 tog ether.
About Inputs and Measurement
• Do not use the instrument with circui ts that exceed its ratings or specifications. Doing so may cause it to become
hot, resulting in bodily injury.
• To av oid electrical hazards and damage to the instrument ,
do not apply voltage exceeding the rated maxim um to the
input terminals.
• The maximum input voltage (and the maximum r ated voltage to earth) for the analog input terminals is 30 V AC rms

Using a CF Card/USB flash drive
• Inserting a CF card/USB flas h drive upside down, backwards or i n the
wrong direction may damage the CF card, USB flash drive, or instrument.
• Never eject a CF card /USB flash drive while measuring or when the

• As the CF card/USB flash drive is sensitive to static elect ricity, damage
to the CF card/USB flash drive or wrong operations by the instrument
may occur due to static electricity. Please be careful when handling it.
