Usage Notes
Usage Notes
Follow these precautions to ensure safe operation and to obtain the full benets of the various
functions.
DANGER
•Do not use the instrument with circuits that exceed its
ratings or specications. Doing so may damage the
instrument or cause it to become hot, resulting in bodily
injury.
•The instrument must not be used to measure current in
high‑voltage lines (1000 V or more). Attempting to do so
could cause a short‑circuit or accident resulting in injury
or death. Also, do not perform measurement around a bare
conductor.
•To prevent an electric shock, do not touch any areas
beyond the barrier while the instrument is in use.

10
Usage Notes
DANGER
•Do not short‑circuit two wires to be measured by bringing the clip or jaw
tip of the connecting cords into contact with them. Arcs or such grave
accidents are likely to occur.
•To prevent an electric shock, be careful to avoid shorting live lines with the
connecting cords tip.
•To prevent a short‑circuit or an electric shock, do not touch the metal part of
the connecting cords tip.
•The maximum measurement current varies with the frequency, and the
current that can be measured continuously is limited. Operating the
instrument at less than this limitation is referred to as derating. Do not
measure currents in excess of the derating curve. Doing so may result in
instrument damage or malfunction, a re, or a burn due to sensor heating.
•It is recommended to make measurements on the secondary side of the
distribution panel. Making measurements on the primary side of the panel,
where currents are higher, poses a higher risk of instrument or equipment
damage in the event of a short‑circuit.

11
Usage Notes
WARNING
•Installing the instrument in inappropriate locations may cause a malfunction
of instrument or may give rise to an accident. Avoid the following locations.
•Exposed to direct sunlight or high temperature
•Exposed to corrosive or combustible gases
•Exposed to a strong electromagnetic eld or electrostatic charge
•Near induction heating systems (such as high‑frequency induction heating
systems and IH cooking equipment)
•Susceptible to vibration
•Exposed to water, oil, chemicals, or solvents
•Exposed to high humidity or condensation
•Exposed to high quantities of dust particles
•Although this instrument is designed to resist the ingress of dust and
dripping water, it is not entirely waterproof or dustproof. Therefore, to prevent
an electric shock, do not use it in a wet or dusty environment.
• Battery may explode if mistreated. Do not short‑circuit, recharge, disassemble
or dispose of in re.

12
Usage Notes
WARNING
•Use only the specied connection cords. Use of any connection cord not
specied by our company does not allow safe measurements.
•To prevent an electric shock, set the rotary switch to the OFF position,
disconnect all connection cords, and remove the instrument from the
measurement object before replacing the batteries.
•To prevent instrument damage or an electric shock, use only the screw for
securing the battery cover in place that is originally installed. If you have lost
a screw or nd that a screw is damaged, please contact your authorized Hioki
distributor or reseller for replacement.
•Options may include connection cords which uses sleeves. To prevent
a short‑circuit accident, be sure to use the connection cords with the
sleeves attached when performing measurements in the CAT III or CAT IV
measurement categories. (See "Measurement categories" (p. 8))
•If the sleeves are inadvertently removed during measurement, stop the
measurement.

13
Usage Notes
CAUTION
•To avoid damage to the instrument, protect it from physical shock when
transporting and handling it. Be especially careful to avoid physical shock due to
dropping it.
•Do not place foreign objects between jaws or insert foreign objects into the gaps of
the sensor head. Doing so may worsen the performances of the sensor or interfere
with clamping action.
•Poor performance or damage from battery leakage could result. Observe the
cautions listed below.
•Do no mix old and new batteries, or different types of batteries.
•Be careful to observe the battery polarity during installation.
•Do not use batteries after their recommended expiry date.
•Do not leave depleted batteries inside the instrument.
• Replace batteries only with the specied type.
•Keep the jaw closed when not in use, to avoid accumulating dust or dirt on the
facing core surfaces, which could interfere with clamp performance.
• The cord is hardened in freezing temperature. Do not bend or pull it to avoid
tearing its shield or cutting cord.
IMPORTANT
Inverter secondary-side waveforms and waveforms that include a large noise component may not be
measured accurately.
