● This instrument can be connected only to the commercial power of
240V+10%-10%, 50Hz.
● For safety reasons, only use the Test Leads designed to be used with
this instrument and recommended by KYORITSU.
● Use only grounded mains outlets to supply the instrument.
Do not touch the device under test while testing is in progress.
● Since a high voltage of 500V is outputting continuously, especially while
measuring insulation resistance, user may get electrical shock.
Also not to touch the capacitor of the device under test as hazardous
voltage may exist.
● When testing, always be sure to keep your fingers behind the safety
barriers on the test leads.
● Disconnect the instrument from the power supply when measurement is
finished.
Do not leave the instrument 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 instrument and return it to your distributor for inspection and repair.
Never attempt to use the instrument if the instrument or your hand is wet.
CAUTION
● When using Test Leads with alligator clip, be sure to check the alligator
clip is firmly connected to the metal part of the device under test.
Otherwise, inaccurate measurement or arc at the contacts may occurs.
● The rated measuring voltage for insulation test is 500V.DC.
For electrical devices to be tested, if this test voltage seems not proper to
apply, contact your distributor and ask for advices.
● When testing faulty device, 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 this
instrument. The device under test is powered on during most tests,
but please turn it to OFF position after use. Use a cloth dipped in water or
neutral detergent for cleaning the instrument.
Do not use abrasives or solvents.

3.1 Productsummary
The Model 6201 is a hand-held portable appliance tester, performing four
functions to ensure the Safety of Class I and Class II appliances. And also can
measure the mains voltage. Readings are displayed on a large liquid crystal
display(LCD) below which are three LEDs, light up in 2color, 2 color LEDs which
unambiguously display a pass or fail indication for results dictated by
international standards.
This instrument is suitable for performing tests as required by the following
standards.
AS/NZS 3760: 2001 In-service safety inspection and testing of electrical
equipment.
This instrument is designed to check the electrical safety of appliances of Class
I and Class II categories.
As a guide IEC standard define these two categories as follows:
Class １：Appliances which have a functional insulation throughout and an
earth connected case. These are often described as earthed
appliances.
Class ２：Appliances which have both functional and additional insulation
where any metal parts cannot become "Live" under fault conditions.

5. Preparationbeforeameasurement
5．1 Visualinspection
Before starting a measurement, user should undertake visual checks on
the mains cord, case and that the correct type and rated fuse is fitted to
the DUT. And also there should be no evidence of damage of a nature
that may impair the electrical safety of the item.
5.2 Connectiontomainpowersupply
5.2.1 Connectionofmainscord
Set the range switch to VOLT range, and connect the mains supply and the
instrument with M7123 mains cord.
M7123
Fig.8
● Always be sure to check there is no abnormal conditions or damages on
CAUTION
the instrument and cords. If any evidence of abnormality found,
measurement shall be stopped immediately.
● The outlet of mains power supply must have earth terminal.
● This instrument can be only connected to the commercial power of
240V+10%-10%, 50Hz.
5.2.2Checkthepowersupplyvoltage
There is no power switch and the instrument is immediately ready for use.
Power supply voltage is displayed on the LCD. Please check the value, and
when it is from 216V to 264V, the instrument can perform correct
measurements. If the displayed value is out of above range, do not make a
measurement.
―11―
● When the voltage of mains power supply is 265V or more, "HI-V" is

WARNING
displayed on the LCD and buzzer sounds (discontinuous sounds). In that
case, disconnect the mains cord of the instrument from main power supply.
5.2.3 NULLsetting
Criteria of judgment for Earth Continuity is 1Ω, and it is low value.
So even the resistance of Test Leads will affect the measurement result.
This instrument, M-6201, can cancel the resistance of Test lead by pressing
250Ｖ/ 500Ｖ
switch. The procedure of NULL setting is shown below.
NULL
The NULL function is not released even if power off the instrument, therefore,
there's no need to do NULL setting at every measurement.
However, when replacing fuses or test leads, it is recommended to do NULL
setting again
Procedure:
(1) Set the range switch to Earth Appliance Test range.
(2) Connect the mains supply and the instrument with M7123 mains cord.
Fig.9

(3) Insert Test Lead with safety alligator clip(M-7129) in to the E terminal of the
instrument, and contact the tip of the Test Lead with the metal parts of the
socket on the instrument.
Press start switch with contacting the Test Lead and the metal parts,the
resistance of Test Lead will be displayed on the LCD as shown above fig.10
for 2sec.
Then, the instrument cancels the resistance value of Test Lead and adjust
the displayed value to "0.00" as shown below fig.10.
At this bout, NULL mark is displayed in the LCD.
