R
This instrument is designed to comply with IEC 61010
Safety Standards, and has been thoroughly tested for
safety prior to shipment. However, 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. We disclaim any responsibility for
accidents or injuries not resulting directly from
instrument defects.
･The symbol printed on the instrument
indicates that the user should refer to a
corresponding topic in the manual (marked
with the symbol) before using the relevant
function.
･In the manual, the symbol indicates
particularly important information that the
user should read before using the instrument.

Measurement categories (Overvoltage categories)
This instrument complies with CAT I safety requirements.
To ensure safe operation of measurement instruments, IEC
61010 establishes safety standards for various electrical
environments, categorized as CAT I to CAT IV, and called
measurement categories. These are defined as follows.
CAT I : Secondary electrical circuits connected to an AC
electrical outlet through a transformer or similar
device.
CAT II : Primary electrical circuits in equipment connected
to an AC electrical outlet by a power cord (portable
tools, household appliances, etc.)
CAT III: Primary electrical circuits of heavy equipment
(fixed installations) connected directly to the
distribution panel, and feeders from the
distribution panel to outlets.
CAT IV: The circuit from the service drop to the service
entrance, and to the power meter and primary
overcurrent protection device (distribution panel).
Higher-numbered categories correspond to electrical
environments with greater momentary energy. So a
measurement device designed for CAT III environments can
endure greater momentary energy than a device designed
for CAT II.
Using a measurement 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 CAT I measuring instrument in CAT II, III, or
IV environments.
The measurement categories comply with the Overvoltage
Categories of the IEC60664 Standards.

DANGE
R
When voltages higher than 30 Vrms, 42.4 Vpeak or
battery circuits with more than 60 VDC are to be
measured, be sure to establish the floating state
first. Carrying out such measurements in the
grounded state involves the risk of electric shock.
When measuring batteries, always ensure sufficient
ventilation. Sometimes sparks may occur when the
test leads are connected to batteries, which can
ignite any accumulated inflammable gases such as
hydrogen.
To avoid electric shock accidents, when measuring
batteries being charged wear proper protective gear
such as rubber gloves.
P
recautions
Follow these precautions to ensure safe operation and to
obtain the full benefits of the various functions.
Preliminary Check
Before using the instrument the first time, verify that it
operates normally to ensure that the no damage occurred
during storage or shipping. If you find any damage,
contact your dealer or Hioki representative.

Precautions
――――――――――――――――――――――――――――――――――
WARNIN
G
Do not allow the instrument to get wet, and do not
take measurements with wet hands. This may cause
an electric shock.
Do not use the instrument where it may be exposed
to corrosive or combustible gases. The instrument
may be damaged or cause an explosion.
Before using the instrument, make sure that the
insulation on the test leads is undamaged and that
no bare conductors are improperly exposed. Using
the instrument in such conditions could cause an
electric shock, so contact your dealer or Hioki
representative for replacements (Model 9465 PIN
TYPE LEAD).
Be sure to connect the SOURCE and SENSE
terminals (banana plugs) correctly. When using the
9460 CLIP TYPE LEAD WITH TEMPERATURE SENSOR,
also connect the TEMP SENSOR terminal (miniplug)
.
See Section 4.2, "Measurement Batteries" for details
of the connections.
To avoid injury or damage to the instrument, do not
attempt to measure AC voltage, or DC voltage
exceeding 60 V.
Do not apply a voltage between the SOURCE(+) and
SENSE(+) or SOURCE(-) and SENSE(-) terminals.
This could result in damage to the instrument.
