2. Features
● This is a Phase indicator and can 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 magnet on th e backside of the i nstrument c an f ix the
instrument onto the distribution board and enables safety and
easy measurements.
● Designed to International safety standard IEC 61010-1 (CAT
III 1000V/ CAT IV, 600V, Pollution degree 2)
3. Instrument layout
● Put insulated protective gears when there is a danger of
electrical shock hazard.
● The tip of clip is made of metal and it is not completely
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.
Otherwise, electrical shock accident may occur.
● Ne ver open the Battery co m pa r tm e n t 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 qualified person can use the instrument at the
secondary side of high voltage power receiving equipments.
# WARNING
● Never attempt to make any measurement, if any abnormal
conditions are noted, such as broken case, and exposed
metal parts.
●
Do not install substitute parts or make any modification 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 barrier on
the instrument to avoid the possible shock hazard.
● Do not t r y to re p lac e bat teri es if t he sur fac e of the
instrument is wet.
● Disconnect the clips from the measured conductors first
and power off the instrument before opening the Battery
compartment cover for a battery replacement.
● Stop using the test lead if the outer jacket is damaged and
the inner metal or color jacket is exposed.
# 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.
● Measurable c ondu ctor size is betwe en dia. 2.4mm and
30mm. Accurate measurements for conductors 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 identify wiring status correctly when an
earth line is connected between phases via delta connection.
Check the connection specification 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.

long period.
● Do not expose the instr ument to dire ct su nlight, high-
temperature 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.
● Never give shocks, such as vibration or drop, which may
damage the instrument.
● Use a damp cloth and detergent for cleaning the instrument.
Do not use abrasives or solvents.
Safety Symbols
#Refer to the instructions in the manual to protect the
user and instrument.
Indicates instrument with double or reinforced insulation
AC
This instrument satisfies the marking requirement defined
in the WEEE Directive. This symbol indicates separate
collection for electrical and electronic equipment.
○ Measurement Category
To ensure safe operation of measuring instruments, IEC 61010
establishes safety standards for various electrical environ-
ments, 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
en t ran ce , a nd to t h e p o we r m ete r an d pr i mar y
overcurrent protection device (distribution panel).

5. Checks and Indications
5.1. Preliminary checks
5.1.1. Press the Power switch and power on the instrument.
Then all the LEDs flash in order for about 1 sec. Confirm
all the L EDs light up and flash. Only the Power LED
keeps lighted up in about 1 sec later.
5.1.2.
Apex of “▼” mark on the Measurement clip shall indicate
the center of the measured conductor. Connect each
Measurement clip to 3-phase line as follows: Red to L1,
Phase-U, White to L2, Phase-V, Blue to L3, Phase-W.
5.1.3. Measure a c overed condu ctor AC70V or m ore fir st
to c onf irm each live LED lig hts up. Do not use the
instrument when any of the LED doesn’t light up.
5.1.4. Prese n c e of live wir es a nd ph as e se q u e nce ar e
informed by LED indication and Buzzer sound as soon
as connecting the clips.
Note:
The label of KEW8035(EU) shows the harmonised and also
the pre-harmonised cable colours (UK):
KEW8035(EU)
KEW8035(EU) shows also other alphanumeric identifications on
the label as:
A B C, R S T and U V W.
5.2. Live wire check
# DANGER
● LEDs don’t light up when voltage to earth is 70V or less.
● Voltages may exist at Earth 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.
State Indication
Live Phase with flashing LED is
live state.
Missing line
or
Earth line
LED doesn’t light up for
missing line or earth line.
Earth line
(Delta
connection）
Phase with flashing LED is
an earth phase.
Positive
phase
When the green Rotation
LED flashes in the order of
the direction 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 Brightness switch to make the LED indication
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 batteries.
● Install batteries in correct polarity as indicated inside the
case.
●
Use the same model of batteries from the same manufacturer.
When the Power LED on the front side of the instrument is
flashing, battery voltage is low. Replace batteries with new
ones to continue further measurements.
Low battery voltage may not affect measurement accuracies.
The instrument is powered off automatically when batteries are
exhausted.
1) Loosen the screw fixing the Battery compartment cover.
2) Slide the Battery compartment cover downwards to remove
it.
3) Replace th e batteries w ith new on es. Four size AA LR6
alkaline or equivalent 1.5V AA type batteries should be used.
4) Install the Battery compartment cover and tighten the screw.
