3. Instrument layout
● Put insul ate d p rot ec tive g ears when t here is a danger of
electrical shock hazard.
● The tip of cl ip is mad e of met al and it is not c omple te ly
insulated. Be especially careful about the possible shorting
where the measured object has exposed metal parts.
● Never attempt to use the instrument if it 's surface or your
hand is wet.
Other wise, electr ical shock accident may occur.
● Nev e r o p e n the Ba t t e r y c ompar t m e nt co v e r an d th e
instrument case when making a measurement.
● The instrument is to be used only in its intended applications
or conditions. Otherwise, safety func tions equipped with the
instrument doesn’t wor k, and instrument damage or serious
personal injur y may be caused.
● Only the q ua li fie d p er son can u se the inst ru ment at the
secondary side of high voltage power receiving equipments.
#
WARNI NG
● Never attempt to make any measurement, if any abnormal
con ditions are not ed, such as broken case, and expos ed
metal par ts.
●
Do not install substitute parts or m ake any mod if ication to the
instrument. Return the instrument to your local Kyoritsu distributor
for repair or re- calibration in case of suspected faulty operation.
● Always keep your fingers and hands behind the bar rier on
the instr ument to avoid the possible shock hazard.
● Do no t tr y to re p l a c e ba t ter i e s if th e su r fa c e o f th e
instrument is wet.

CAUTION
● Do not apply shocks, vibrations or excessive forces onto the
Measurement clips.
● Never force to open the Measurement clips when they are
frozen.
● This instrument can be operated with safe at temperatures
between -10ºC and 50ºC 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.
● Me as ura ble con duc to r size is b et w ee n dia. 2.4 mm and
30mm. Ac cur ate measurements for co nductor s out of this
range cannot be made.
● Measured results are influenced 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 identif y wir ing status correctly when an
earth line is connected bet ween phases via delta connection.
Check the connection specif ication 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. Other wise, it may cause a malfunc tion.

5. Checks and Indications
5.1. Preliminary c hecks
5.1.1. Press the Power switch and powe r on the instrument.
Then all the LEDs flash in order for about 1 sec. Confirm
all the LEDs l ig ht up and flash. Only the Power LED
keeps lighted up in about 1 sec later.
5.1.2. Ap e x of “▼” ma r k on th e Me a s u reme n t cl i p sh a l l
indicate the center of the measured conductor. Connect
ea ch M eas ur e me nt c lip to 3 - p ha se l in e as f ol l ow s:
Red to L1, Phase -U, White to L2, Phase-V, Blue to L3,
Phase -W.
5.1.3. Meas ur e a c o ve red cond uc t or AC70V or m ore firs t
to conf irm e ac h liv e LED lig ht s up. Do n ot u se t he
instrument when any of the LED doesn’t light up.
5.1.4. Pr e s e n c e of live wi r e s an d phase se q u e n c e ar e
informed by LED indication and Buzzer sound as soon
as connecting the clips.
5.2. Live wire check
#
DANGER
● LEDs don’t light up when voltage to earth is 70V or less.
● Voltages may exist at Ear th phase.
#
CAUTION
● It is impossible to detect the missing phase of the earth line.
Earth line and phase sequence are indicated if the earth line
has a missing phase.

Phase with flashing LED is
an earth phase.
Positive
phase
When the green Rotation
LED flashes in the order of
the direc tion indicated by
the arrow mark (clockwise),
the circuit under test has a
positive phase.
The buzzer sounds
intermittently. (pi-pi-pi
）
Reversed
phase
When the red Rotation
LED flashes in the order
of the direction indicated
by the arrow mark
(counterclockwise), the
circuit under test has a
reversed phase. The buzzer
sounds continuously. (pi- --)
5.3. Use the B right ne ss switc h to make the LED i nd ic ati on
brighter.
Brightness of all the LEDs (except for the Power LED) is
increased while pressing down the switch.
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 bat teries.
● Inst all batteries in co rrect polar it y as indic ate d in side the
case.
●
Use the same model of batteries from the same manufacturer.
Whe n t he Power LED on th e f ront s ide of the i nstrume nt is
flash ing, b at ter y volta ge is low. Replace batt eries wi th new
ones to continue further measurements.
Low bat tery 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) Rep la ce the batteri es with new ones . Fou r s ize A A LR6
alka li ne or equival en t 1.5 V A A t yp e batt eri es shoul d b e
used.
4) Install the Batter y compartment cover and tighten the screw.
