Electricity is dangerous and can cause injury and death. Always treat it with the
greatest of respectand care. If you are not quite sure how to proceed, stop a
measurement and take advice from a qualified person.
This instruction manual ontains warning and safety rules which must be
observed by the user to ensure safe operation of the instrument and retain it in
safe condition. Therefore, read through these operating instructions before
using the instrument.

IMPORTANT:

This instrument must only be used by a competent and trained person and
operated in strict accordance with the 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 the
instructions or with the safety procedures.

● 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.

2. Procedureofremovingcover

Model 6201 have a dedicated cover to protect against an impact from the
outside and prevent the operation part, the LCD, and the connector socket from
becoming dirty. The cover can be detached and put on the back side of the
main body during measurement.

3. Productsummaryandexplanation

3.1 Productsummary

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.

（1）Testsocket

Insert the mains plug of DUT to this socket for the polarity test of protective
conductor resistance, insulation resistance and Extension leads.

（2）Terminal block

Connect the attached mains cord and Test Leads to this terminal block.

（3）Terminal for mains cord

This terminal is connected to a mains supply via M7123.

（4）Terminal for Extension leads adaptor

It corresponds to L, N, E of test socket, and the extension leads adaptor(M-

7140) connected with the cord reel to be plugged to it.

（5）Rpe terminal

Connect the Test Lead with alligator clip(M7129)(13) to this terminal for the
measurement of protective conductor resistance, and clip the metal parts of
DUT with the alligator clip.

（6）LCD

Measured value is displayed.

（7） LED for test result

When the value of protective conductor resistance and insulation resistance
exceeds the limit dictated by applicable standards, LED lights up in red.
When it is within the limit, LED lights up in green.

（8）Start switch

A measurement starts by pressing this switch.

（9）NULL/250V-500V switch

● Earthed appliance test measurementIt is used in order to push the

NULL button before protection earth resistance measurement and to
cancel the resistance of a test leads.

● Double insulation test measurement

The test voltage of insulation resistance is changed to 500V and 250V.

（10）Range switch

Select a range with this switch.
