Introduction
Accuracy labeling
The instrument accuracy’s is expressed by dening a percentage of the reading, a percentage
of full scale, and limit value for errors in terms of digits.
Reading
(displayed value)
Indicates the value displayed by the instrument. Limit values for reading errors
are expressed as a percentage of the reading (“% of reading” or “% rdg”).
Full scale
(maximum display value)
Indicates the maximum display value for each measurement range.
Measurement range values for the instrument indicates that maximum display
value. Limit values for full-scale errors are expressed as a percentage of full
scale (“% of full scale” or “% f.s.”).
Digit
(resolution)
Indicates the minimum display unit (in other words, the smallest digit that can
have a value of 1) for a digital measuring instrument. Limit values for digit errors
are expressed using digits (“digits” or “dgt”).
Screen display
The instrument screen displays the alphanumeric characters as follows.

Precautions for Use
Precautions for Use
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.

Precautions for Use
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.
HIOKI CM3286C961-00

13
Precautions for Use
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
•Use only the specied connection cords. Use of any connection cord
not specied by our company does not allow safe measurements.
•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. (For measurement
categories, see p. 10.)
•If the sleeves are removed during measurement, stop the
measurement.
HIOKI CM3286C961-00

14
Precautions for Use
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.
• Do not get the instrument wet or operate it if your hands are wet. Doing so may
cause electric shock.
• 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.
