Indicates AC (Alternating Current).
Indicates DC (Direct Current).
Indicates both DC (Direct Current) and AC
(Alternating Current).
Indicates a device which is double-
insulated.
Safety Symbols
f.s. (maximum display or scale value, or length of scale)
Signifies the maximum display (scale) value or the
length of the scale (in cases where the scale consists

Attentions During Use
DANGER
･
･･
･Use clamp testers only on power lines up to 600
Vrms AC, to avoid short-circuits and accidents
that could result in injury or death.
･
･･
･Do not use clamp testers on bare conductors.
When the clamp core jaw is open, there is a risk
of short-circuits and accidents that could result
in injury or death.
･
･･
･Always connect the clamp sensor to the
secondary side of a breaker. On the secondary
side of a breaker, even if the lines are shorted
the breaker can trip and prevent an accident.
On the primary side, however, the current
capacity may be large, and in the event of a
short-circuits there may be a serious accident.
･
･･
･When using an AC adapter, use only a specified
AC adapter, HIOKI model 9445 (UP01211090,
POTRANS).
Attentions During Use
In order to ensure safe operation and to obtain
maximum performance from the unit, observe the
cautions listed below.

Attentions During Use
WARNING
･
･･
･To prevent electric shock, do not allow the unit
to become wet and do not use the unit when
your hands are wet.
･
･･
･To avoid electric shock accidents, when
carrying out measurement on live lines, wear
proper protective gear, including insulating
rubber gloves, insulating rubber boots, and
safety helmet, and use extreme caution.
･
･･
･During current measurement, to avoid an
electric shock accident, do not connect the test
leads to the unit.
･
･･
･Do not input voltage exceeding 600 Vrms (1000
V max.).
･
･･
･To avoid electric shock when replacing the
batteries, first disconnect the clamp portion
from the object to be measured. Also, after
replacing the batteries, always replace the back
case before using the unit.
･
･･
･When replacing the batteries, be sure to insert
them with the polarity correct.
･
･･
･Do not short-circuits used batteries,
disassemble them, or throw them in a fire.
Doing so may cause the batteries to explode.
･
･･
･Be sure to dispose of used batteries according
to their type in the prescribed manner and in the
proper location.
