We dene measurement tolerances in terms of f.s. (full scale), rdg. (reading), and setting values
with the following meanings:
f.s. (maximum display value
or scale length)
rdg. (reading or displayed
value)
Setting Indicates the value set as the output voltage, current, or other quantity.
The maximum displayable value or scale length.
For this instrument, the maximum displayable value equals the numerical
number of a presently set range (unit: V/div) multiplied by the number of divisions (20) on the vertical axis.
Example: When the range is set to 1 V/div, f.s. = 20 V
The value currently being measured and indicated on the measuring
instrument.
Measurement Categories
To ensure safe operation of measuring instruments, IEC 61010 establishes safety standards
for various electrical environments, categorized as CAT II to CAT IV, and called measurement
categories.
DANGER
• Using a measuring 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 measuring instrument that lacks category labeling 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 electrical
circuits in equipment connected to an AC electrical outlet with a power cord (portable
tools, household appliances, etc.)
CAT III: When measuring the primary electrical circuits of heavy equipment (xed 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 (distribution panel)

Operation Precautions
Handling the Instrument and Modules
• Do not use the modules or the cables with circuits that exceed those ratings or
specications.
Doing so may damage the instrument or cause it to become hot, resulting in
bodily injury.
Even including any devices, such as an attenuator, in the input terminal will
never increase the maximum rated voltage to earth. Take care of the connection
not to allow any input voltage to exceed the maximum rated voltage to earth.
• To avoid an electric shock, do not remove the instrument’s cover and the
modules’ cases.
The internal components of the instrument carry high voltages and may
become very hot during operation.
• To avoid an electric shock, before removing or replacing an input module,
conrm that the instrument is turned off and that the connection cords are
disconnected.
• To avoid the danger of an electric shock, never operate the instrument with an
input module removed. To use the instrument with a module removed, install a
blank panel over the opening of the removed module.
• To prevent the instrument damage or an electric shock, use only the screws
that are originally installed for securing the module in place.
If you have lost any screws or nd that any screws are damaged, please contact
your Hioki distributor for a replacement.
DANGER
WARNING
CAUTION
• To avoid damage to the instrument, protect it from physical shock when
transporting and handling it. Be especially careful to avoid physical shock due
to dropping it.
• The mounting screws must be rmly tightened or the module may not perform
to specications, or may even fail.
• To avoid damaging modules, do not touch the connectors, installed in the
instrument, to which the modules are connected.
• Before carrying the instrument, disconnect all cables and remove the CF card, USB
ash drive, and the recording paper.
• Displayed waveforms can frequently uctuate due to induction potential even when no
voltage is applied. This, however, is not a malfunction.
• 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 interference to the reception of radio and television broadcasts.
Handling the printer and the recording paper
WARNING
The print head and surrounding metal parts can become hot. Be careful to avoid
touching these parts.

Storing data recordings
The recording paper is thermally sensitive. Observe the following precautions to avoid paper discoloration
and fading.
• To avoid paper discoloration, do not expose it to direct sunlight. Store the paper at no more than 40°C
and 90% RH.
• Store the paper away from dew and damp places.
• Make photocopies of recording printouts that are to be handled or stored for legal purposes.
• If the thermal paper is exposed to an organic solvent such as alcohol or ketone, it may no longer
develop properly, and recorded data may fade. Keep the printer papers away from exible PVC lms
and pressure sensitive tapes including scotch tapes because they contain organic solvents.
• Also, the thermal recording paper is ruined by contact with wet diazo copy paper.
Avoid exposure to direct
sunlight.
Do not store the paper at
more than
40°C (104°F) and 90%

• With some external storage device, the instrument may not start up if it is turned on while the
external storage device is inserted. In such a case, turn on the instrument rst, and then insert
the external media. Prior testing is recommended.
• The instrument does not support particular kind of USB ash drives, such as those that require
ngerprint authentication or a password.
• When saving or loading data, insert the storage device before selecting data to be saved.
When the storage device is not inserted, no devices are not displayed in the le list.
• All storage devices (built-in drive [SSD], USB ash drive, and CF card) have a limited service
life. After extensive use for a long period, saving and loading data may be disabled. In that
case, replace the device with a new one.
• The built-in drive (SSD) is a consumable part. When the saved data reaches the capacity (about
60 TB), no further data can be recorded. In such a case, the SSD should be replaced with a
new one.
• When the instrument is left powered off for a one year or more, the data saved on the built-in
drive (SSD) may be lost. Be sure to back up the data if the instrument is left powered off for a
long time.
• Devices the automatic data saving supports are the built-in drive (SSD), a USB ash drive, and
a CF card.
• Data can also be automatically saved on a USB ash drive; however, we recommend using
Hioki optional CF card instead for data protection.

Before connecting cables
Operation Precautions
DANGER
When measuring power line voltage
• Connect the connecting cables to only the secondary side of a breaker. Even
if a short-circuit occurs on the secondary side of the breaker, the breaker will
interrupt a short-circuit current. Do not connect them to the primary side of the
breaker because an unrestricted current ow could damage the instrument and
facilities if a short circuit occurs.
• To prevent an electrical shock and a bodily injury, do not touch any input
terminals on the VT (PT), CT or the instrument when they are in operation.
• Do not leave the measurement cables connected to the instrument in an
environment where voltage surges exceeding the maximum input voltage may
occur. Subjecting the instrument to such a voltage may result in damage to the
instrument or a serious accident.
• Do not short-circuit two wires to be measured by bringing the connection
cables into contact with them. Arcs or such grave accidents are likely to occur.
• To avoid a short-circuit or an electric shock, do not touch the metal parts of the
connecting cable clips.
• To avoid electrical shock, be careful to avoid shorting live lines with the
connection cable chips.
WARNING
To avoid an electric shock and a short-circuit accident, use only the specied test
leads to connect the instrument input terminals to the circuit to be tested.
• To avoid an electric shock, do not exceed the lower of the ratings shown on the
instrument and connection cords.
