The KEW6016 incorporates Anti Trip Technology (ATT) which electronically bypasses
RCDs when performing loop impedance tests. This saves time and money by not having
to take the RCD out of the circuit during testing and is a safer procedure to follow.
With the ATT function enabled , a test of 15mA or less is applied between line & earth. It
enables loop impedance measurements without tripping RCDs rated at 30mA and above.
Please read this instruction manual carefully before using this equipment.

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.
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 these instructions.
They must always be observed when using the instrument.
3 This instrument is designed to work in distribution systems where the line to earth has a
maximum voltage of 300V 50/60Hz and for some ranges where line to line has a
maximum voltage of 500V 50/60Hz.
Be sure to use it within this rated voltage.
For use in the continuity testing and insulation testing modes this instrument must be
used ONLY on circuits which are de-energized.
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 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.
8 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.
9 When testing, always be sure to keep your fingers behind the finger guards on the test
leads.
10 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.

2
11 Do not operate the function selector while 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.
12 Do not rotate rotary switch 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.
13 Always check the test lead resistance before carrying out tests. This ensures the leads
are ok before taking measurements. The resistance of leads and/or crocodile clips may
be significant when measuring low resistances. If crocodile clips can be avoided for low
resistance measurements, this will reduce the error due to lead accessories
14 When carrying out Insulation Resistance tests, always release the test button and wait for
charged capacitances to totally discharge before removing the test leads from the test
circuit.

4. FEATURES
The KEW6016 Multi-Function tester performs eight functions in one instrument.
1 Continuity tester
2 Insulation resistance tester
3 Loop impedance tester
4 Prospective short circuit current tester
5 RCD tester
6 Voltage tester
7 Phase rotation tester
8 Earth tester
Continuity function has the following features:
Live circuit warning “Live Circuit” warning on the display.
Fuse Protection Continuity Function has a fuse protection function to prevent a
fuse blow at live working. With this function, a fuse rarely blow
while measuring continuity on live conductors.
Continuity Null Allows automatic subtraction of test lead resistance from
continuity measurements.
Continuity 2Ω Buzzer Buzzer sounds at 2Ω or less at Continuity function.
(Switchable on or off)
Insulation function has the following features:
Live circuit warning “Live Circuit” warning on the display.
Auto discharge Electric charges stored in capacitive circuits are discharged
automatically after testing by releasing the test button.
Insulation Resistance

PSC/PFC 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°) half cycle of voltage. This selector is used in the
RCD mode to obtain the maximum trip time of an RCD for the
test selected.
UL value selector Select UL (limit of contact voltage) 25V or 50V. Where Uc
(contact voltage) exceeds UL value at RCD testing, “Uc > UL”
will be displayed without starting the measurement.
ALL testing functions have the following
Touch Pad Gives an alert, when touching the Touch Pad, while the PE terminal
is connected to Line by mistake.
Memory Function Save the measured data in the internal memory.
The data can be edited on a PC by using Communication Adapter
Model8212USB and PC Software “KEW Report”.
Auto power off Automatically switches the instrument off after a period of
approximately 10 minutes. The Auto power off mode can only be
cancelled by switching the instrument on again.

7. CONTINUITY (RESISTANCE) TESTS
WARNING
Ensure that circuits to be tested are not live.
Disconnect the instrument from the circuit under test before operating the function
switch.
To select the low resistance range select ‘CONTINUITY’.
7.1 Test Procedure
The object of continuity testing is to measure only the resistance of the parts of the wiring
system under test. This measurement should not include the resistance of any test leads
used. The resistance of the test leads needs to be subtracted from any continuity
measurement. The KEW6016 is provided with a continuity null feature which allows
automatic compensation for any test lead resistance.
You should only use the test leads supplied with the instrument.
