Safety Information
Safety Information
This instrument is designed to conform to IEC 61010 Safety
Standards and has been thoroughly tested for safety prior to
shipment. However, using the instrument in a way not described in
this manual may negate the provided safety features.
Carefully read the following safety notes before using the
instrument.
DANGER
Familiarize yourself with the instructions
and precautions in this manual before use.
Failure to do so could cause improper use of the
instrument, resulting in serious bodily injury or damage
to the instrument.

Safety Information
WARNING
If you have not used any electrical
measuring instruments before, you should
be supervised by a technician who has
experience in electrical measurement.
Failure to do so could cause the user to experience an
electric shock.
Moreover, it could cause serious events such as heat
generation, re, and an arc ash due to a short-circuit.
Protective gear
Use appropriate protective insulation.
Performing measurement using this instrument involves
live-line work. Failure to use protective gear could
cause the operator to experience an electric shock.
Using protective gear is prescribed under applicable
laws and regulations.
HIOKI DT4261A961-00

Safety Information
Measurement categories
To ensure safe operation of measuring instruments, IEC 61010
species the measurement categories, which classies testing and
measuring circuits into three categories according to the types of
mains circuits to which they are intended to be connected.
DANGER
Do not use a measuring instrument for
measurements on a mains circuit that
exceeds the range of the measurement
category rated for the instrument.
Do not use a measuring instrument
without a measurement category rating for
measurements on a mains circuit.
Failure to observe this can cause a serious bodily injury
and damage to the instrument and other equipment.
This instrument conforms to the safety requirements for CAT III
1000 V, CAT IV 600 V measuring instruments.
Measurement category II (CAT II)
Applicable to test and measuring circuits connected directly to
utilization points (socket outlets and similar points) of the low-
voltage mains installation.
EXAMPLE: Measurements on household appliances, portable tools,
and similar equipment, and on the consumer side only
of socket-outlets in the xed installation.
HIOKI DT4261A961-00

12
Safety Information
Measurement category III (CAT III)
Applicable to test and measuring circuits connected to the
distribution part of the building’s low-voltage mains installation.
EXAMPLE: Measurements on distribution boards (including
secondary meters), photovoltaic panels, circuit breakers,
wiring, including cables, bus-bars, junction boxes,
switches, socket-outlets in the xed installation, and
equipment for industrial use and some other equipment
such as stationary motors with permanent connection to
the xed installation.
Measurement category IV (CAT IV)
Applicable to test and measuring circuits connected at the source of
the building’s low-voltage mains installation.
EXAMPLE: Measurements on devices installed before the main
fuse or circuit breaker in the building installation.

Precautions for Use
Installation
WARNING
Do not install the instrument in locations
such as the following:
• In locations where it would be subject to direct sunlight
or high temperatures
• In locations where it would be exposed to corrosive or
explosive gases
• In locations where it would be exposed to powerful
electromagnetic radiation or close to objects carrying
an electric charge
• Close to inductive heating devices (high-frequency
inductive heating devices, IH cooktops, etc.)
• In locations characterized by a large amount of
mechanical vibration
• In locations where it would be exposed to water, oil,
chemicals, or solvents
• In locations where it would be exposed to high humidity
or condensation
• In locations with an excessive amount of dust or metal
particles
