1. Safe testing
Electricity is dangerous and can cause injury and death. Always
treat it with the greatest of respect and care. If you are not quite sure
how to proceed, then stop, take advice from a qualified person.
This instruction manual contains warning and safety rules which
must be observed by the user to ensure safe operation of the Tester
and retain it in safe condition. Therefore, read through these
operating instructions before using the Tester.
IMPORTANT:
The Tester must only be used by a competent and trained person
and operated in strict accordance with these instructions.
KYORITSU will not accept liability for any damage or injury caused
by misuse or non-compliance with the instructions or with the safety
procedures.
It is essential to read and to understand the safety rules contained
in these instructions and with the safety procedures.
The symbol # indicated on the Tester means that the user must
refer to the related sections in the manual for safe operation of the
Test e r.
Be sure to carefully read instructions following each symbol # in
this manual.
# DANGER : is reserved for conditions and actions that are likely
to cause serious or fatal injury.
# WARNING: is reserved for conditions and actions that can
cause serious or fatal injury.
# CAUTION : is reserved for conditions and actions that can
cause injury or instrument damage.
# DANGER
● The Tester can be connected only to the commercial power of
100V – 253V, 50Hz.
● For safety reasons, only use the Test Leads designed to be
used with this Tester and recommended by KYORITSU.
● Use only grounded mains outlets to supply the Tester.
● Do not touch the device under test while testing is in progress.

Page 5
# DANGER
●
Since a high voltage 250V or 500V is being output continuously,
when measuring insulation resistance, the user may get an
electrical shock. Any capacitors in the appliance under test may
become charged during testing and may contain hazardous
voltages do not touch them.
● When testing, always be sure to keep your fingers behind the
safety protective finger guard on the test leads.
●
Disconnect the Tester from the power supply when measurement
is finished.
● Do not leave the Tester with connected to the power supply.
# WARNING
●
Never open the instrument case – because dangerous voltages
are present. Only fully trained and competent electrical engineers
should open the case.
● If abnormal conditions of any sort are noted (such as a faulty
display, unexpected readings, broken case, cracked test leads,
etc.) do not use the Tester and return it to your distributor for
inspection and repair.
● Never attempt to use the Tester if the Tester or your hands are
wet.
● Stop using the test lead if the outer jacket is damaged and the
inner white jacket is exposed.
# CAUTION
● When using Test Leads with the alligator clip, be sure to check
the alligator clip is firmly connected to the metal part of the
device under test. Otherwise, inaccurate measurements or
arcing at the contacts may occur.
● The rated measuring voltage for the insulation test is 250V or
500V DC. If this voltage seems too high for the appliance
under test contact the appliance manufacturer for advice.
● When testing a faulty appliance, it may trip the circuit breaker
of main power supply during test and may cause interruption of
service. Be careful when the same main power supply is used
for PCs.
● We are not liable for loss of data on PC during testing with the
Tester. The appliance under test is powered on during most
tests, but please turn it to the OFF position after testing.
● Use a very slightly damp cloth for cleaning the Tester. 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 over-current
protection device (distribution panel).
O: Device which is
not directly
connected to the
mains power supply

4. Preparation before a measurement
4.1 Visual inspection
Before starting a measurement, the user should undertake visual
checks on the mains lead, case and that the correct type and rated
fuse is fitted to the appliance under test. There should also be no
evidence of damage of a nature that may impair the electrical safety
of the appliance.
4.2 Batter y Voltage Check
(1) Insert batteries with reference to 11. Batter y/ Fuse replacement
in this manual.
(2) Hold down Power switch 1 sec. to turn on the Tester.
(3) Check the battery indicator displayed in the upper left corner of
the LCD.
If just the last one segment of the indicator remains, the battery
voltage is extremely low. Refer to 11. Battery/ Fuse replacement
and replace batteries to perform further measurements.
If an empty battery indicator is displayed, the battery voltage is
lower than the working voltage limit. Replace batteries immediately
to keep accurate measurement.
Battery recommendation:
Use of alkaline battery is recommended. Use of other type of
batteries may cause improper indication of battery level.
4.3 Setting
4.3.1 Null setting
AS/NZS3760 pass level for Protective conductor resistance is 1 Ω,
which is a low value. So even the resistance of Test Leads will affect
the measurement result.
The Tester can cancel the resistance of test lead by pressing
The procedure of Null setting is shown below. The Null function is
held in memory even when the Tester is turned off, so theres no
need to Null the lead resistance every time. However, when replacing
fuses or test leads, it is recommended to do a Null setting again.
NULL
.
Note:
Null setting is possible at both Class l Test and Extension Lead
Test. However, only one Null value can be held in memory. For
example, when the Null setting is carried out at Class l Test, the set
value will also be used for Extension Lead Test (unless it is reset).
(1) Insert Test Lead with probe (MODEL7161A) into the Rpe Test
Lead terminal of the Tester, and contact the tip of the Test Lead
with the earth contacts of the socket on the Tester.
(2) Press NULL switch on any screen.
18
Page 20
(3) The screen switches to NULL screen, and NULL measurement
starts. The LCD shows blinking MEAS mark and measured
value during a measurement. The measured value is saved and
subtracted from the further measured values.
(4) If the measured value is less than 3 Ω, previous NULL value is
cleared and a new value is saved. When 3 Ω or higher is
measured, previous NULL value is just cleared (NULL mark
disappears).
4.3.2 Voltage setting for insulation resistance measurement
(How to change between 250V and 500V)
Two different rated voltages, 250 V and 500 V, are available for
insulation resistance test. Press 250V/500V switch on the stand-by
screen or while measured result is being displayed at CL I/ CL II/
Extension lead test. Default setting is 250 V.
Sets to 500 V.

# WARNING
● When conducting a leakage test the appliance will automatically
power on and will operate in its normal manner. It is imperative
that the appliance is secured safely before the test is carried
out. Extra care needs to be taken with appliances which have
heating elements and rotating parts.
● Firmly insert the plug of the appliance to the socket of the
Tester. Plugs may get hot if Leakage current test is performed
with improper connection.
● Do not connect/remove the plugs during Leakage current test.
It may cause a reading error.
● Do not use the Tester on the device which has a power
consumption of 2.5 kVA or more.
# CAUTION
● Where DUT ON Check function detects that DUT is off, blinking
OFF?appears in the LCD and the test is stopped. Turn on

# CAUTION
● Follow the procedure described in 4.3.1 and do Null setting
before a measurement, but use the short MODEL7276 lead
instead of the MODEL 7129A test lead, by plugging the
MODEL 7276 into the Extension Lead Adaptor terminal and
the AU socket on the front of the unit.
● When the terminal is open or the resistance value exceeds
the measuring range, > (over range display) appears on
the LCD.
● Do not touch the device under test while testing is in progress.
Since a high voltage of 250V or 500V will be present, the user
may get an electrical shock.

5.4 RCD TEST
(1) PRCD test
This test is to test and confirm a PRCD (Portable Residual
Current Device) trips within the rated time by applying specified
current. The Tester incorporates a circuit to test PRCD with
Rated Tripping Current (IΔn) of 10 mA or 30 mA. PRCD trip time
is measured in sequence: ×1(0°)→×1(18 0°)→×5(0°)→×5(180°).
After each test, reset the tripped PRCD to proceed to the next
test. PASS result is given where the PRCD tripped within the
rated time through all the tests.
Press the RCD switch
PRCD

to perform RCD test.
# CAUTION
● The Tester can test RCDs rated at 230V+10％, -15%. Input

● Check the connection if symbol is displayed in the LCD.
Connection may be incorrect and a test doesnt start even RCD
switch is pressed.
● If " IΔn" setting is greater than the rated residual current of the
RCD, the RCD will trip and "no" may be displayed on LCD.
● Special conditions of RCDs of a particular design, for example
S- type, should be taken into consideration.
● ATT (Anti-Trip Technology)
The KEW6205 uses mains voltage across L-N for PRCD testing.
It enables PRCD testing without tripping the RCD of mains power.
It works with the connection for "(1) PRCD test" as shown above;
doesn't work with the connection for "(2) PRCD test via socket outlet".
(2) PRCD test via socket outlet
Make connection as the following illustration indicates when
testing a PRCD connected to a socket outlet. For this test, use
MODEL7276 for connection.

Press the RCD switch to
perform RCD test.
● If a fault voltage exceeds 50 V while applying a test current to test
a bu ilt - in type RCD, the LC D sho w sUf. Hi and the test is halted.
● If a voltage exists between the protective conductor and earth, it
may influence the measurements.
● If a voltage exists between neutral and earth, it may influence the
measurements, therefore, the connection between neutral point
of the distribution system and earth should be checked before
testing.
● The potential fields of other earthing installations may influence
the measurement.
● Resistance of earthed electrodes in the circuit under test with a
Probe - auxiliary earthed electrode - should be 200Ω or less.
● Equipment following the RCD, e.g. capacitors or rotating
machinery, may cause a significant lengthening of the measured
trip time.
