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.

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 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

minor injury or instrument damage.

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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.

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. Procedureofremovingcover

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 Productsummary

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 Instrumentlayout(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.

―

（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.
