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.

7. Measuringmethod
7.1 Measuringprotectiveconductorresistance(RPE)
The measurement of protective conductor resistance is of course not possible
for devices which are not equipped with a protective conductor (e.g. Safety
Class ll and III devices).The objective of this test is to ensure the connection
between the earth or the protective conductor of the commercial power earth
pin and the metal casing and accessible conductive parts of the DUT is
satisfactory and of a low enough resistance value to satisfy safety standards.
And this measurement should be done also by reversing the output polarity.
(1) Connect the DUT as described in clause 6.
(2) Set the range switch to the "RPE 20Ω+" position.
(3) Read the measured value in "Ω" from the LCD.
(4) Set the range switch to the "RPE 20Ω-" position.
(5) Move the cable from the DUT during a measurement, section by
section over its entire length, in order to locate interruptions.
Results
Protective conductor resistance may not exceed the following values.
Maximum allowable protective conductor resistance values depending on
cable length
Under no circumstances may a value of 1Ω be exceeded. The table is also
valid for cable reels and extension cables.
CAUTION
● Follow the procedure described in 5.2-4 and do NULL setting before a
measurement.
● Alligator clip must make good contact with the enclosure of the DUT.
● When the terminal is open or the resistance value exceeds measuring
range, "OL" mark (over range display) appears on the LCD.

7.2 Measuringinsulationresistance(RINS)
This measurement may only be performed if the DUT has successfully
completed protective conductor resistance testing (Safety class l device). The
objective of this test is to ensure that the insulation between Phase or Neutral
conductor of the mains power supply and the metal casing and accessible
conductive parts of the DUT is satisfactory.
(1) Connect the DUT as described in clause 6. If it is a Class II or III device,
connect the PE/2mA terminal and exposed metal parts with Test Lead.
(2) Switch the DUT on.
(3) Set the range switch to "RINS 200MΩ" position.
(4) Read the measured value in "MΩ" from the LCD.
Results
Insulation resistance may not fall short of below values.
This instrument has LED indications which illuminate when the resulting
measurement is below the DUT threshold value of 0.5MΩ or 2.0MΩ.
(according to DIN VDE 0702)
CAUTION
● When the terminal is open or the resistance value exceeds measuring
range, "OL" mark (over range display) appears on the LCD.
● Depending on the type of DUT, insulation resistance value is unstable
and the indication may not become stable. In that case, regard the
measured value as a reference value.
● Do not touch the DUT while testing is in progress. Since a high voltage of
500V is outputting continuously, user may get electrical shock.

components to which voltage is applied during operation and exposed metal
parts may not exceed 7mA, or 15mA for devices with heating power of greater
than or equal to 6kW.
This instrument has LED indications which illuminate when the resulting
measurement is below the DUT threshold value of 7.0mA or 15.0mA.
(according to DIN VDE 0702)
CAUTION
● This instrument performs a "substitute leakage" test by applying a safe
test voltage of AC30V between Phase or Neutral and the earth connector
of the DUT. The results are displayed as thought the DUT would be
powered from a supply voltage of 230V. The resultant measurement is to
be accepted as advisory and not as an absolute measurement.
● Devices that are fitted with a differential mains filter will display the value
which is greater than the actual value.
