Safety Notes
Safety Notes
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
Mishandling during use could result in injury or death,
as well as damage to the instrument. Familiarize
yourself with the instructions and precautions in this
manual before use.
WARNING
Electricity can potentially cause serious events such
as an electric shock, heat generation, re, and an arc
ash due to a short-circuit. If you have not used any
electrical measuring instruments before, you should
be supervised by a technician who has experience in
electrical measurement.

Safety Notes
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. Failure to observe this can cause a
severe accident.
•Do not use a measuring instrument without a
measurement category rating for measurements on
a mains circuit. Failure to observe this can cause a
severe accident.
This instrument conforms to the safety requirements for CAT II 300 V,
CAT III 150 V, CAT IV 100 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 FT6031B961-00

9
Safety Notes
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.

Usage Notes
Usage Notes
Observe the following precautionary information to ensure that the
instrument can be used safely and in a manner that allows it to
perform as described in its specications.
Use of the instrument should conrm not only to its specications,
but also to the specications of all accessories, options, batteries,
and other equipment in use.
Verifying before usage
DANGER
If the test lead or the instrument is damaged, there
is a risk of an electric shock. Perform the following
inspection before use:
•Check that the insulation of the test leads are
neither ripped nor torn and that no metal parts
are exposed. Using the instrument under such
conditions could result in an electric shock. Replace
the test leads with those specied by Hioki.
•Check the instrument for any damage that may have
occurred during storage or shipping, and perform
functional checks before use.

Usage Notes
The protection rating for the enclosure of the instrument (based on
EN60529) is IP65/67*.
CAUTION
Although the instrument has a dust-proof, jet-proof and
waterproof structure, it is not for completely shutting out
the water intrusion into the inside. Please note that it can
be a cause of failure.
*IP65/IP67:
This indicates the degree of protection provided by
the enclosure of the device against use in hazardous
locations, entry of solid foreign objects, and the ingress of
water.
6: Protected against access to hazardous parts with wire
measuring 1.0 mm in diameter. Dust-proof type (Dust shall
not penetrate the enclosure.)
5: The equipment inside the enclosure is protected against
the harmful effects of water projected in jets against the
enclosure from any direction.
7: Watertight (Quantities of water that may harm the enclosure
when it is temporarily immersed in water shall not penetrate
the enclosure.)
For details on the operating temperature and humidity range, see
the specications. (p. 67)

Usage Notes
Handling the cables
CAUTION
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.
The ends of the L9787 Test Lead and L9840 Auxiliary
Earthing Rod are sharp. Be careful to avoid injury.
IMPORTANT
Use only the specied auxiliary earthing rod, cables, and test
leads. Using a non-specied cable may result in incorrect
measurements due to poor connection or other reasons.
Precautions during measurement
WARNING
If the instrument is used in locations where the rating
indicated on the instrument or cords is exceeded, the
instrument may be damaged resulting in personal
injury. Do not use the instrument in such locations.
See “Measurement categories” (p.8)
Precautions during shipment
Be sure to follow these precautions when transporting the
instrument:
• Remove accessories and optional equipment from the instrument
in order to avoid damage. Additionally, use the original packing
materials, and be sure to double box the instrument. Accidental
damage suffered in transit is not covered by the warranty.
• Attach a description of the issue when sending out your
instrument for repair.
