cause minor injur y or instr ument damage.
● Confir m a pr oper operation of the instrument with a we llknown power supply.
● Warning LED might not light up at live status. (earth potential
70V or less). Never touch the wire.
● Voltages may exist when the Live LED is f lashing (indicating
Earth phase). Never touc h with the wires.
● Never make mea suremen t on a circuit in w hic h the ear th
potential exceeds 100 0V to avoid electrical shocks.
● Do not make measurement when thunder is rumbling. If the
instrument is in use, stop the measurement immediately and
remove the instrument from the measured object.
● Do not attempt to make measu rem ent in the presence of
flammable gasses. Otherwise, the use of the instrument
may cause sparking, which can lead to an explosion.
● Keep your fingers and hands behind the barrier on the
instrument to avoid the possible shock ha zard.

DANGER
#
● Put insul ate d protecti ve gears when there is a da nger of
electrical shock hazard.
● The ti p of cl ip is ma de of metal an d it is not c om pl etely
insulated. Be especially careful about the possible shorting
where the measured object has exposed metal parts.
● Never attempt to use th e instrument if it's surface or your
hand is wet.
Other wise, electrical shock accident may occur.
● Never open the Battery compartment cover and the
instrument case when making a measurement.
● The instrument is to be used only in its intended applications
or conditions. Otherwise, safety functions equipped with the
instrument doesn’t work, and instrument damage or serious
personal injury may be caused.
● Only the qual if ied p er so n can use the inst rume nt at the
secondary side of high voltage power receiving equipments.
WARNI NG
● Never attempt to make any measurement, if any abnormal
con dit ion s are noted, such as bro ken case, and exp ose d
metal par ts.
●
Do not install substi tute par ts or make any modifi cat ion to the
instrument. Return the instrument to your local Kyoritsu distributor
for repair or re-calibration in case of suspected fault y operation.
● Always keep your fingers and hands behind the barrier on
the instr ument to avoid the possible shoc k hazard.
● Do n ot try to repl ac e batteri es if the sur face o f the
instrument is wet.
Disco nnect the clips from the measu red condu ctors fi rst
and power of f th e instr ument before op ening the Ba tter y
compar tment c over for a battery replacement.
● Do not apply shocks, vibrations or excessive forces onto the
Measurement clips.
● Never force to open the Measurement clips when they are
frozen.

between -10ºC and 50 ºC and altitude up to 2000m.
● Keep away from dust and water.
● Precise measurement cannot be made near a charged body
or equipment generating electromagnetic waves.
● Measurable conductor size is between dia. 2.4mm and
30mm. Accurate measurem ents for conductors out of this
range cannot be made.
● Measured results are inf luenced by voltage wires on which
twice or more of the measured voltages exist near the point
to be clipped.
The clip point should be far from such voltage wires.
●
This instrument cannot identify wiring status correctly when an
earth line is connected bet ween phases via delta c onnection.
Check the connection specific ation of the measured object.
● Incapable of measuring bus bars or shielded wires. Clip onto
a covered conductor and make a measurement.
●
All the clips should be clipped onto the covered wires and
make measurements. Otherwise, it may cause a malfunction.
#
CAUTION
#
● Do not touch the Clips during measurements to get accurate
results.
● This instrument cannot find the missing line of the earth line.
Do not pull the cable when removing the Measurement clips
●
from the measured conductors. It may cause a break in cable.
● Power off the instr ument af ter use. Remove the bat ter ies
if the instrument is to be stored and will not be in use for a
long period.
● Do not expose the instrument to direct sunlight, hightemperature and humidity or dew.
● Dry and store the instrument if it is wet.
● Do not step on or pinch the cord to prevent the jacket of
cable from being damaged.
● Bending or pulling the cord may cause a break in a cord.
● Neve r give shocks, su ch as v ibr ati on or d rop, which may
damage the instrument.
● Use a damp cloth and detergent for cleaning the instrument.
Do not use abrasives or solvents.

○ Measurement Category
To ensure safe operation of measuring instruments, IEC 61010
establishes safety standards for various electrical environments, categorized as O to CAT.IV, and called measurement
categories. Higher-numbered categories correspond to electrical
environments with greater momentary energy, so a measuring
instrument designed for CAT.III environments can endure greater
momentary energy than one designed for CAT.II.
O : Circuits which are not directly connected to the mains
power supply.
CAT.II : Electrical circuits of equipment connected to an AC
electrical outlet by a power cord.
CAT.III : Primary electrical circuits of the equipment 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
overcurrent protection device (distribution panel).

2. Features
● This is a Phase indic ator and c an indicate a presence of live
line and phase sequence with the equipped LED and Buzzer
while clipping the 3-phase line over the jacket of a conductor.
● Brightness switch is equipped to make the indication visible
in dimly lit areas.
● A ma gn et on the back si de of the inst rument can fix th e
instrument onto the distribution board and enables safety and
easy measurements.
● Designed to International safety standard IEC 61010-1 (CAT.

6. Battery Replacement
CAUTION
● Power off the instrument and remove the Measurement clips
from the measured object when replacing batteries to avoid
electrical shocks.
● Do not mix old and new batteries.
● Inst all batterie s in corre ct polarity as indicated inside the
case.
Use the same model of batteries from the same manufacturer.
●
Whe n th e Power LED on the fron t si de of t he instr ument is
flashing, batte ry voltage is low. Repla ce batteri es with new
ones to continue further measurements.
Low battery voltage may not affect measurement accuracies.
The instrument is powered off automatically when bat teries are
exhausted.
1) Loosen the screw fixing the Battery compartment cover.
2) Slide the Battery compartment cover downwards to remove
it.
3) Re place th e batteries with new ones . Fo ur size AA LR6
alkaline or equivalent 1.5V AA type batteries should be
used.
4) Install the Batter y compartment cover and tighten the screw.
