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

Operation Precautions
HIOKI MR8847G961-07
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.
• It is recommended to measure the secondary side of a distribution panel with
the U8974 High Voltage Unit. Do not connect the connection cords on the
primary side of the distribution panel because an unrestricted current ow can
damage the connection cords and facilities if a short-circuit occurs.
DANGER
WARNING
• Each channel of Model U8979 Charge Unit has the BNC terminal and miniature
connector terminal with the common ground. Do not connect cords with each
of the terminals simultaneously to avoid a short-circuit.
• 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.
• Setting the measurement mode to [PreAmp] allows Model U8979 Charge Unit
to constantly provide power (3.0 mA, 22 V) to sensors. Set any measurement
mode other than [PreAmp] or tum off the instrument before connecting a
sensor or probe with a BNC terminal to avoid an electric shock or damage to
the measurement target.

Operation Precautions
HIOKI MR8847G961-07
CAUTION
• To avoid damaging modules, do not touch the connectors, installed in the instrument,
to which the modules are connected.
• Model U8979 Charge Unit has miniature connectors with the maximum input charge
of ±500 pC (for six higher-sensitivity range) or ±50,000 pC (for six lower-sensitivity
range). Inputting a charge that exceeds these value causes damage to the instrument.
• Use an acceleration sensor with a built-in pre-amplier that conforms to the
specication of Model U8979 (3.0 mA, 22 V). Using a inapplicable sensor may cause
damaging itself.
• 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.
• 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.

CAUTION
Be careful not to cut yourself with the paper cutter.
• Please use only the specied recording paper. Using non-specied paper may not only result in
faulty printing, but printing may become impossible.
• If the recording paper is skewed on the roller, paper jams may result.
• Always use the paper cutter to cut the printed paper. Excessive paper dust can accumulate on
the roller if the paper is cut with the print head, which may result in paper jams or white streaks
in the printing.
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%
RH.
Avoid exposure to volatile
organic solvents like
alcohol, ethers, and
ketones.
Avoid contact with exible
PVC lms or adhesive
tapes such as scotch
tapes.
Storing recording paper
• Store thermal paper where its temperature will not exceed 40°C.
• The paper will deteriorate if exposed to light for a long time; thus, do not remove the wrapping paper
from the roll until it is ready to be used.

Operation Precautions
HIOKI MR8847G961-07
Before connecting cables
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.
DANGER
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.
To prevent an electric shock, conrm that the white or red portion (insulation
layer) inside the cable is not exposed. If a color inside the cable is exposed, do
not use the cable.
CAUTION
• The cable is hardened in the freezing temperatures. Do not bend or pull it to avoid
tearing its shield or cutting cable.
• Connecting cables to the BNC jacks on modules
• Do not use any cable terminated with a metal BNC connector. If you connect a metal
BNC cable to an insulated BNC connector, the insulated BNC connector and the
instrument may be damaged.
To prevent cable damage, do not step on cables or pinch them between other objects.
Do not bend or pull on cables at their base.
12
IMPORTANT
• Use only the specied connection cables. Use of any cable not specied by our company does
not allow safe measurements due to poor connection or other reasons.
• For detailed precautions and instructions regarding connections, refer to the instruction
manuals for your modules, connection cables, etc.
