or if it fails to operate accordin g to the specificati ons, contact
your dealer or Hioki representative.

Preliminary Checks

• Before using the p roduct the first time, ve rify tha t it operate s
normally to ens ure th at the no da ma ge oc curred durin g s tor­age or shipping. If you fin d an y damage , c ontact yo ur de aler
or Hioki representative.

• Before using the pro duct, make sure that the insulation o n
the leads is undamaged and that no bare conductors are
improperly expos ed. Using the product in such conditions
could cause an electric shock, so contact your dealer or Hioki
representative for repair.

Safety

Follow these precautions to ensure safe operation and to
obtain the full benefits of the various functions.

This product is designed to conform to 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 product. Be certain that you unde r­stand the instructions and precautions in the man­ual before use. We disclaim any responsibility for
accidents or injuries not resulting directly from
product defects.

Measurement categories (Overvoltage categories)

This product complies with CAT IV (300 V) , CAT III (600 V) safety
requirements.
T o ensure safe operation of measurement products, IEC 61010 estab­lishes safety standards for various elect rical 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 overcur rent 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 product in an environment designated w ith a
higher-numbered category than t hat for which the product is rated
could result in a severe accident, and must be carefully avoided.
Never use a CAT I measuring product in CAT II, III, or IV environ­ments.
The measurement categories comply with the Overvoltage Categories
of the IEC60664 Standards.

shock.

• Always verify the appropriate setting of t he Func­tion Selector before connecting the test leads.

• D isconnect the test le ads from the measur ement
object before switching the Function Selector.

• Never apply voltage to test leads when the Resis­tance or Continuity Check functions are selected.
Doing so may damage the product and result in
personal injury. To avoid electrical accidents,
remove power from the circuit before measuring.

Voltag e Measurement

• The maximum input voltage is 600 V DC/ 600

voltage in excess of the maximum input could
destroy the product and result in personal injury
or death.

• To avoid electrical shock, be careful to avoid
shorting live lines wit h the test leads.

• For sa fety, test lead connections must always be
made at the secondary side of a circuit breaker.

• The ma ximum rated voltage between input termi­nals and ground is 600 V DC/AC. Attempting to
measure voltages exceeding 600 V with respect to
ground could damage the product and result in
personal injury.
