1.Safetesting
！
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.
Therefore, read through these operating instructions before using the
instrument.
IMPORTANT:
1．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.
2．It is essential to read and to understand the safety rules contained in the
instructions or with the safety procedures.
3．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
230V+10%-10%, 50/60Hz.
● For safety reasons, only use the Test Leads designed to be used with this
instrument and recommended by KYORITSU.
● Mains power supply to which the instrument is connected must be
protected with a fuse or a breaker of 16A (max. rating) against over load.
● 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.
● Not to exceed max. throughput of 4000VA on current consumption (ILINE)
range of M-6202.
● Disconnect the instrument from the power supply when measurement is
finished. Do not leave the instrument with connected to the power supply.
！
WARNING
● Never opentheinstrument 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.
KYORITSU is 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. Procedureofremovingcover
Model 6200 and 6202 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.

3.1 Productsummary
Model 6200, 6202 perform tests and measurements in accordance with DIN
VDE 0701:2000 (Repair, modification and testing of electrical instruments) and
DIN VDE 0702:1995 (Repeat tests for electrical instruments). These standards
require to measure protective conductor resistance, insulation resistance and
equivalent leakage current of repaired or modified equipment or to test the
absence of voltage at the exposed metal parts of information technology
equipment and office machine. This instrument can perform voltage
measurement of main power supply, in addition to above measurements. For
M-6202, it can perform current consumption measurement.
This instrument is designed to check the electrical safety of the devices of
Safety Class I, Class II and Class III categories. As a guide IEC standard define
these three categories as follows:
Class l ：Devices which have a functional insulation throughout and an earth
connected case. These are often described as earthed devices.
Class ll ：Devices which have both functional and additional insulation where
any metal parts cannot become "Live" under fault conditions.
Class Ⅲ：Devices in which protection against electrical shock rely upon supply
from SELV circuit and in which hazardous voltage are not generated.
Note) SELV (safety extra low voltage) circuit is designed and protected that
under normal operating conditions, single fault condition and when basic
insulation is damaged, its voltage do not exceed a safe voltage.

3.4 Instrumentlayout(Illust:M-6202)
（1）Test socket
If the device under test (hereinafter, referred as "DUT" in this document) is
equipped with a mains plug, the measurement of protective conductor
resistance, insulation resistance, equivalent leakage current and contact
current can be performed.
（2）Terminal block
The supplied mains plug and Test Leads can be connected to this terminal.
And this terminal can be used when making a measurement with an
optional cord.
―6―
（3）Terminal block / Terminal for mains cord
The supplied mains cord can be connected to this terminal.
（4）Terminal block / L/N terminal
This terminal wired in parallel to two short-circuited Phase terminals at the
test socket (1).
The DUT Phase conductors can be connected to this L/N terminal and
measured, if the DUT is not equipped with a mains plug.
（5）Terminal block / PE/2mA terminal
Contact current at exposed conductive parts which are not connected with
protective conductor can be measured by connecting RPE-Test Lead. In
addition, this terminal is wired in parallel to the protective conductor
terminal at the test socket (1), so the DUT protective conductor can be
connected to this terminal, if the DUT earth terminal is not equipped with a
mains plug. Beyond this, exposed conductive parts at the DUT must be
connected to this terminal for insulation testing and the measurement of
equivalent leakage current.
（6）Terminal block / RPE-Test Lead terminal
RPE-Test Lead for resistance measurement of the protective conductor can
be connected to this terminal, and the alligator clip is to be connected with
the enclosure of the DUT.
（7）LCD
Measured values are displayed.
（8）LED for threshold value
The red LED lights up when limit values defined in the applicable standards
have been exceeded during the measurement of protective conductor
resistance, insulation resistance, equivalent leakage current and contact
current.
（9）NULL button
NULL setting shall be done before starting the measurement of protective
conductor resistance. (Cancel the resistance of the Test Lead, inside
protective fuse and so on.)
（10）Range switch
Select a range with the range switch.
