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.
• 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 Primary electrical circuits in equipment con-
nected to an AC electrical outlet by a power
cord (portable tools, household appliances,
etc.) CAT II covers directly measuring elec-
trical outlet receptacles.
CAT III Primary electrical circuits of heavy equip-
ment (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 ser-
vice entrance, and to the power meter and
primary overcurrent protection device (dis-
tribution panel).

Operating Precautions
Follow these precautions to ensure safe operation and to
obtain the full benefits of the various functions.
Before using the instrument, verify that it
operates normally to ensure that no dam-
age occurred during storage or shipping. If
you find any damage, contact your autho-
rized Hioki distributor or reseller.
During shipment of the instrument, handle it
carefully so that it is not damaged due to a
vibration or shock.
Preliminary Checks
If the test lead or the instrument is dam-
aged, there is a risk of electric shock.
Perform the following inspection before
using the instrument:
• Before using the instrument check that
the coating 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
electric shock. Replace the test leads
with those specified by our company.
• Verify that the instrument operates nor-
mally to ensure that no damage
occurred during storage or shipping. If
you find any damage, contact your
authorized Hioki distributor or reseller.
• To prevent an electric shock, confirm
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.

or otherwise result in a serious
accident.
• To avoid short circuit or electric shock,
do not touch the metal parts of the
connecting cable clips.
• To prevent electric shock, when mea-
suring the voltage of a power line use
only the specified test lead.
• The optional test leads provided with
this instrument conform to the safety
standard EN61010. Use a test lead in
accordance with its defined measure-
ment category and rated voltage.
• To prevent an electric shock, do not
exceed the lower of the ratings shown
on the instrument and test leads.
To avoid damage to the instrument, do not
apply voltage or current to temperature
probe.
