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,
stop a measurement and 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 instrument and retain it
in safe condition.
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 underst
instructions or with the safety procedures.
The symbol # indicated on the instrument means that the user must refer to
the related sections in the manual for safe operation of the instrument.
Be sure to carefully read instructions following each symbol # in this manual.

DANGER

• 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 th

• 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.

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

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 liabl e f or loss of data on P C d ur ing testing wit h t hi s
instrument. The device under test (DUT) is pow
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

KEW 6201A 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 KEW 6201A 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 2 color, 2 color LEDs
which unambiguously display a pass or fa
international standards.
This instrument is suitable for performing tests as required by the following
standards.
AS/NZS 3760: 2010 In-s ervice safety inspection and testin g of elect rical
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 foll

Class I : Applianc es which have a function al insulatio n t hr oughout and

an earth connected case. These are often described as earthed
appliances.

Class II: Appli ances which have both functional and additional insulation

where any metal parts cannot become Live under fault conditions.
