Purpose of the Tests
Ground Bond Test
This test is to ensure the connection between the ground wire and ground
pin in the power cord of the product and the metal casing are connected by
a sufficiently low impedance.
A test current is applied between the ground pin of the power cord and the
ground clip.
A high current is normally used to stress the connection to a fault condition.
The length of the test is limited to prevent damage due to overheating.
Short to Case Test
A low voltage test to ensure there is no short present between the line
conductor and the case.
Short to Line Test
A low voltage test to ensure there is no short between the line and neutral
conductors.
Leakage Test
A supply voltage test to ensure there is no harmful leakage in the equipment
under test.
Extension Cord Test
This test confirms the safety and integrity of 120V power cords.
The cord test performs a ground bond test on the ground wire and then
does continuity and polarity checks on the Line and Neutral conductors,
between the plug and socket of the extension cord.

Definitions
• Equipment Under Test - the electrical / electronic apparatus (EUT)
which is the subject of testing.
• Tester - the Clare Safe Check 5s tester.
• Un-powered Tests - the EUT is the subject of electrical tests using
stimuli generated within the Tester.
• User - The test operative using the Tester to perform tests on an EUT
Switching on the Tester
• Connect the power cord to a 120 Volt 60Hz Grounded supply.
• Switch on the Tester.
• The amber test indicators should illuminate.
• If the Green PASS and Red FAIL indicators illuminate there is a fault.
Supply Power Outlet faults
• If a fault is detected, indicated by the Green PASS and Red FAIL
indicators, switch the tester off immediately and correct the fault. Seek
assistance if you are unsure how to proceed.
• The tester will not allow you to perform any tests while a fault is present.
• The type of fault can be determined by the buzzer.
o Buzzer Continuous – Mains power has been connected to
the male test plug. Remove any power cords connected to
the tests connectors
o Short beeps (0.2s duration) – Supply Ground fault. The
installation ground has a fault. Consult a qualified
electrician.
o Long beeps (0.5s duration) – Line/Neutral fault. The
installation line and neutral connections are crossed.
Consult a qualified electrician.

Using the Tester
WARNING - do not touch or hold the EUT during testing. Ensure the EUT
cannot move when under test.
Testing Metal Case (Class 1) Products
• Before connecting to the Tester a visual inspection must be carried out
to ensure the EUT has no loose cables on plugs or cable entries, and to
verify the condition of the supply cord.
• Connect the EUT to the appropriate test output socket.
• Ensure the EUT is switched on and properly supported.
• Connect the ground clip to a metal part on the body of EUT.
• WARNING During LEAKAGE tests the product will be powered at line
voltage and will operate. Make sure the ground clip is not connected to
moving parts.
• Press and hold the TEST button to begin test sequence. If the TEST
button is released at any time the sequence will be aborted.
• If any test fails all outputs are switched off and the FAIL indicator will
flash for 3 seconds accompanied by the buzzer sounding.
• As each test is performed the indicator will flash. When a test is
complete the next test in the sequence will start automatically.
• After the SHORT to LINE test has finished the LEAKAGE test will not
start until the TEST button has been released and the RUN/LEAKAGE
button has been pushed.
• Press and hold the RUN/LEAKAGE button to start the LEAKAGE test. If
the RUN/LEAKAGE button is released at any time the test sequence will
abort.
• WARNING During LEAKAGE tests hazardous voltages may be
present. Do not touch the EUT during LEAKAGE tests.
• When all tests are successfully completed the PASS indicator will flash
for 3 seconds.
Testing Double Insulated (Class 2) Products
• Before connecting to the Tester a visual inspection must be made to
ensure the EUT has no loose cables on plugs or entries, and to verify
the condition of the supply cord.
• Connect the EUT to the appropriate test output socket.
• Ensure the EUT is switched on and properly supported.
• Connect the ground clip to body of EUT.

• Press and hold the TEST button to begin. If the TEST button is
released at any time the sequence will abort.
• If any test fails all outputs are switched off and the FAIL indicator will
flash for 3 seconds accompanied by the buzzer.
• As the SHORT to LINE test is performed the indicator will flash.
• After the SHORT to LINE test has finished the LEAKAGE test will not
start until the TEST button has been released and the RUN/LEAKAGE
button has been pushed.
• Press and hold the RUN/LEAKAGE button to start the LEAKAGE test. If
the RUN/LEAKAGE button is released at any time the test sequence
will abort.
• WARNING During LEAKAGE tests hazardous voltages may be present.
Do not touch the EUT during LEAKAGE tests.
Testing Extension Cords
• Before connecting to the Tester a visual inspection must be made to
ensure the EUT(in this case the extension cord set) has no loose cables
on plugs or sockets, and to verify the condition of the supply cord.
• Connect the socket end of the EUT to the Tester output plug (male) and
the plug end of the EUT to the appropriate test socket output.
• Press and hold the TEST button to begin the tests (three stages). If the
TEST button is released at any time the sequence will abort.
• As the CORD TEST is performed the indicator will flash to indicate that
the Ground bond test (1st stage), then the continuity & polarity tests (2nd
stage), then the line/neutral short test (3rd stage) are being performed
respectively.
• If any test fails all outputs are switched off and the FAIL indicator will
flash for 3 seconds accompanied by the buzzer.
• When all tests are successfully completed the PASS indicator will flash
for 3 seconds.
RUN/LEAKAGE Test – Self Test Facility
• Ensure there are no EUTs connected to the tester.
• Select CLASS 2 Double Insulated – using the rotary switch.
• Press and hold the TEST button to begin. If the TEST button is
released at any time the sequence will abort.
• After the SHORT to LINE test has finished the LEAKAGE test will not
start until the TEST button has been released and the RUN/LEAKAGE
button has been pushed.

• Before beginning the LEAKAGE test press the Leakage Self Test button
on the rear of the tester
• Press and hold the RUN/LEAKAGE button to start the LEAKAGE test. If
the RUN/LEAKAGE button is released at any time the test sequence
will abort.
• The LEAKAGE test should fail Note: the Leakage Self Test button must
be pressed for the full duration of the LEAKAGE test
• If the LEAKAGE test does not fail, contact Clare Instruments Inc. for
