3 Performing Tests
Press CLI and CLII keys simultaneously to switch on
the PAC3760 DL. When the unit is ready the display
will be as shown below.
PAC3760 DL
3.1 Testing a Class I Appliance
Visually inspect the appliance as per requirements of
AS/NZS 3760:2010. If the appliance passes a visual
inspection proceed with the electrical tests.
Plug the earth test lead into the Earth Continuity test
terminal on the PAC3760 DL end panel.
Plug the appliance into the PAC3760 DL front panel
test socket.
Connect the earth test lead to an exposed metal part
on the appliance.
If the Appliance under test has an ON/OFF switch,
make sure it is in the ON position.
Press the Class I test button to start a Class I test
sequence.
The PAC3760 DL will now test the continuity of the
protective earth.
If the measured value is greater than the 1 ohm pass/
fail threshold, the measured value is displayed and the
unit indicates a fail result as shown below.

Operating Instructions
11
If the measured value is less than or equal to the 1 ohm
pass/fail threshold, the measured value is displayed
and the unit indicates a pass result, as shown below.
PAC3760 DL
If the Earth Continuity test has passed then the unit
will proceed with an Insulation test.
Note: The power switch on the appliance under
test must be in the ON position to perform
an insulation test. If no appliance is detected
the PAC3760 DL will display LO LOAd.
If the LO LOAd enunciator is displayed, the load
presented by the appliance may be too small for the
PAC3760 DL to detect. In this case, press the Class I
test button to continue.
If the Insulation test measures below the 1Mohm
pass/fail threshold, the measured value is displayed
and the unit indicates a fail.

Operating Instructions
12
If the measured value is greater than or equal to the
1 Mohm pass/fail threshold, the measured value is
displayed and the unit indicates a pass result.
3.2 Testing a Class I Appliance with Leakage
Visually inspect the appliance as per requirements of
AS/NZS 3760:2010. If the appliance passes a visual
inspection proceed with the electrical tests.
Plug the mains lead into the PAC3760 DL and a mains
supply socket.
When plugging the mains lead into the
PAC3760 DL ensure that the polarity
orientation of the connector is correct.
DO NOT FORCE THE PLUG INTO THE
CONNECTOR, doing so may damage the
PAC3760 DL.
Plug the earth test lead into the Earth Continuity test
terminal on the PAC3760 DL end panel.
Plug the appliance into the PAC3760 DL front panel
test socket.
Connect the earth test probe to an exposed metal
part on the appliance.
If the Appliance under test has an ON/OFF switch,
make sure it is in the ON position.
Press and hold the Leakage button and then the Class
I test button.
The PAC3760 DL will now test the continuity of the
protective earth.
If the measured value is greater than the 1 ohm pass/
fail threshold, the measured value is displayed and the
unit indicates a fail.
If the measured value is less than or equal to the 1 ohm
pass/fail threshold, the measured value is displayed
and the unit indicates a pass result.
The unit will proceed with a Leakage test.

If the LO LOAd enunciator is displayed, the load
presented by the appliance may be too small for the
PAC3760 DL to detect. In this case, press the Leakage
button to continue.
Note: If the High Load enunciator is displayed,
the load presented by the appliance may
be too great for the PAC3760 DL and users
should carry out an insulation test.

placed next to the ILEAK enunciator.
The FAIL enunciator is illuminated.
If the Leakage current is less than or equal to 5mA a
tick is placed next to the ILEAK enunciator.

sequence.
Note: The power switch on the appliance under
test must be in the ON position to perform
an insulation test. If no appliance is detected
the PAC3760 DL will display LO LOAd.
If the LO LOAd enunciator remains on the display,
the load presented by the appliance may be too small
for the PAC3760 DL to detect. In this case, press the
Class II test button to continue.

3.5 Testing a mains cord
Visually inspect the appliance as per requirements
of AS/NZS 3760:2010. If the cord passes a visual
inspection proceed with the electrical tests.
Plug the mains cord under test into the IEC socket
and the front panel mains socket on the PAC3760 DL.
Press the Class I test sequence button.
The PAC3760 DL will first test the continuity of the
protective earth.
If the measured value is greater than 1 ohm a cross is
placed next to the
RPE enunciator, a FAIL is indicated.
If the measured value is less than or equal to 1 ohm a
tick is placed next the RPE enunciator.
The unit will proceed with the Insulation test.
If the Insulation Resistance is less than 1 Mohm a
cross is placed next to the RISO enunciator.
If the Insulation Resistance is greater than or equal to
1 Mohm a tick is placed next to the RISO enunciator.
The unit will proceed with the wiring test, checking the
live and neutral conductors for short or open circuits
or reversed connections.
If the wiring is correct a tick is placed next to the cord
enunciator, the GOOd enunciator is illuminated and a
PASS is indicated for the sequence.
PAC3760 DL
Note: If the tested cord has a wiring fault, one
of the following enunciators will be
illuminated in place of GOOd
OPEn indicates that either the live or neutral
conductor is broken (open circuit) or the plug top
fuse has blown

Operating Instructions

Shrt indicates that the live and neutral conductors
are shorted together
CrOS indicates that the live and neutral connections
are crossed (live and neutral conductors reversed)
3.6 Testing an extension lead
Visually inspect the appliance as per requirements
of AS/NZS 3760:2010. If the cord passes a visual
inspection proceed with the electrical tests.
Plug the supplied 0.5m IEC lead into the IEC socket
and into a mains outlet on the extension lead. Plug the
mains plug of the extension lead into the front panel
mains socket on the PAC3760 DL.
The extension lead can now be tested in the same
manner as an IEC as described above.
3.7a Test an EPOD (Powerboard)
Visually inspect the appliance as per requirements of
AS/NZS 3760. If the cord passes a visual inspection
proceed with the electrical tests. AS/NZS 3760
requires an earth resistance test to be performed to
each outlet.
Operators have the choice of carrying out two test
sequences for EPODs:
Procedure A: a complete test sequence is carried
out for every socket (earth, insulation
and polarity)
Procedure B: a complete test sequence is carried
out on the very last socket. Only an
earth resistance test is carried out on
the remaining sockets.
