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
and take advice from a qualified person.

●The symbol on the instrument means that the user must refer to the

relevant section of this instruction manual for safe operation of the
instrument.

●Pay particular attention to all WARNINGS and CAUTIONS in this instruction

manual.
WARNING indicates warnings to avoid electric shock and CAUTION indicates
cautions to avoid damage to the instrument.

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 non­compliance with the instructions or with the safety procedures.

2．It is essential to read and to understand the safety rules contained in the

instructions. They must always be observed when using the instrument.

3．This instrument is intended only for single phase operation at 230V AC ±

10% phase to earth or phase to neutral operation, and then only for loop
and RCD testing. For use in the continuity testing and insulation testing
modes this instrument must be used ONLY on circuits which are de-

energised.

4．When conducting tests do not touch any exposed metalwork associated

with the installation. Such metalwork may become live for the duration of
the test.

5．Never open the instrument case (except for fuse and battery replacement

and in this case disconnect all leads first) because dangerous voltages are
present. Only fully trained and competent electrical engineers should open
the case. If a fault develops, return the instrument to your distributor for
inspection and repair.

6．If the overheat symbol appears in the display ( ) disconnect the

instrument from the mains supply and allow to cool down.

7．For loop impedance tests to prevent unwanted tripping during loop testing

all residual current devices（RCD's）must be taken out of the circuit and
temporarily replaced with a suitably rated MCB unit. The RCD must be
replaced after the loop test is completed.

―2―

8．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
tester and return it to your distributor for repair.

9．For safety reasons only use accessories (test leads, probes, fuses, cases,

etc) designed to be used with this instrument and recommended by
KYORITSU. The use of other accessories is prohibited as they are unlikely
to have the correct safety features.

10．When testing, always be sure to keep your fingers behind the safety

barriers on the test leads.

11．During testing it is possible that there may be a momentary degradation of

the reading due to the presence of excessive transients or discharges on
the electrical system under test. Should this be observed, the test must be
repeated to obtain a correct reading. If in doubt, contact your distributor.

12．The sliding shutter on the back of the instrument is a safety device. The

instrument should not be used if it is damaged or impaired in any way, but
returned to your distributor for attention.

13．Do not operate the function selector whilst the instrument is connected to

a circuit. If, for example, the instrument has just completed a continuity
test and an insulation test is to follow, disconnect the test leads from the
circuit before moving the selector switch.

14．Do not rotate function dial when test button is depressed. If the function

switch is inadvertently moved to a new function when the test button is
depressed or in lock-down position the test in progress will be halted. To
reset, release test button and press again to restart testing on new
function.

15．Use a damp cloth and detergent for cleaning the instrument. Do not use

abrasives or solvents.

16．Before using the instrument, please insert the batteries rightly in

accordance with the "9. BATTERY REPLACEMENT" of page 24.
When not installing batteries, all the functions of the instrument don't
work.

Model 6010A Multi-Function tester performs five functions in one instrument.

1．Continuity tester
2．Insulation resistance tester
3．Loop impedance tester
4．RCD tester
5．Mains voltage warning when operating the loop impedance and RCD

mode.

The tester is designed to Safety Standard IEC 61010-1／EN 61010-1 CAT III
(300V).

Dust proof construction in conformance with IP50, IEC529.

The instrument is supplied with:

-

1．A KAMP10 lead for loop/RCD testing at socket outlets.
2．Model 7025 lead for insulation and continuity testing.

In the insulation resistance testing mode the instrument provides a rated current
of 1mA as required in

IEC 61557-2／EN 61557-2 1997.

In the continuity testing mode the instrument provides a short circuit current of
200mA as required in

IEC 61557-4／EN 61557-4 1997.

Continuity and insulation resistance functions have the following features:-

Live circuit warning A colour coded LED warns if the circuit under

test is live.

Auto discharge Electric charges stored in capacitive circuits

are discharged automatically after testing by
releasing the test button.

Test current Warning Beeper Warns when the test current exceeds

200mA

(IEC 61557-4)during continuity measurement.

Loop impedance and RCD testing functions have the following features:-

Voltage level In the loop impedance mode, supply voltage

is displayed when the instrument is connected
to the supply until the test button is pressed.

Wiring check Three LEDs indicate if the wiring of the circuit

under test is correct.

―5―

Over temperature protection Detects overheating of the internal resistor

(used for loop and RCD tests) and of the
current control MOS FET (used for RCD
tests) displaying a warning symbol ( ) and
automatically halting further measurements.

Phase angle selector The test can be selected from either the

positive (0™) or from the negative (180™) half­cycle of voltage. This will prevent tripping of
some polarised RCDs when loop testing and
may give a more accurate reading when
testing RCDs.

Auto data hold Holds the displayed reading for a time after

the test is complete.

Auto power off Automatically switches the instrument off after

a period of approximately 1 minutes.

V-NE Monitoring Circuit Automatically aborts measurement when the

N-E voltage rises to 50V or greater on RCD
ranges.

Optional Accessory OMA DIEC distribution board or lighting circuit

test lead for LOOP／RCD testing.
