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

5. Preparation before a measurement

5.1 Visual inspection

  Before starting a measurement, user should undertake visual checks on

the mains cord, case and that the correct type and rated fuse is fitted to
the DUT. And also there should be no evidence of damage of a nature
that may impair the electrical safety of the item.

5.2 Connection to main power supply

 5.2.1 Connection of mains cord

Set the Function switch to VOLT Function, and connect the mains supply
and the instrument with M7123 mains cord.

Fig. 8

M7123

CAUTION

• Always be sure to check there is no abnormal conditions or damages
on the instrument and cords. If any evidence of abnormality found,
measurement shall be stopped immediately.

• The outlet of main power supply must have earth terminal.

• This instrument can be only connected

240V+10%-10%, 50Hz.

 5.2.2 Check the power supply voltage

   There is no power switch and the instrument is immediately ready for

use. Power supply voltage is displayed on the LCD. Please check the
value, and when it is from 216V to 264V, the instrument can perform
correct measurements. If the displayed value is out of above range, do
not make a measurement.

• When the voltage of main power supply is 265V or more, HI-V is
displayed on the LCD.

• In that case, disconnect the mains cord of the instrument from main
power supply.

 5.2.3 Null setting

   A criteria of judgment for Earth Continuity is 1Ω, and it is low value.

So even the resistance of Test Leads will affect the measurement result.

   This instrument, M-6201A, can cancel the resistance of Test lead by

pressing Null|250V/500V
shown below.

   The Null fu nct ion is not re leased even if power off the instrument,

therefore, there's no need to do Null setting at every measurement.

   However, when replacing fuses or test leads, it is recommended to do

Null setting again.

Procedure:

⑴ Set the function switch to Class I Test function.
 ⑵

Connect the mains supply and the instrument with M7123 mains cord.

• Operate a device and measure the leakage current flowing on it at
Leakage current test function. Care should be taken not to touch with
the heating or movable parts during tests. Extra care should also be
taken to light and heat generated by the device.

• Firmly insert the plugs of DUT to the AU socket of this instrument.
Plugs may be he at ed if Leakage curre nt test is performed with
improper connection.

• Do not connect/remove the plugs during Leakage current test. It may
cause reading error. Do not use the instrument on the device which
has a power of 2kVA or more.

6.6 Leakage Current Test

This function is to conduct the leakage current test separately with DUT
operating actually. A leakage current only will be displayed on the LCD after
DUT is electrified for 15 seconds.

D will not light on even the Class I, Class II thresholds are exceeded.

 • Set the function switch to Leakage Current Test position.

 • Refer to the Fig12 or Fig13 for connection of an appliance.

 • After set up is done, press

 • Check the switch of DUT is ON.

 • DUT will operate for 15 seconds, and the maximum value of the leakage

current will be displayed on the LCD. If the leakage from the DUT is
greater than 20mA then the 6201A should immediately stop the test.

• In order to stop the Leakage Current Test, press
again. The test will stop. A message Stp appears on the LCD but values
