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 fi rst test the continuity of the
protective earth.
If the measured value is greater than 1 ohm a cross is
placed next to the
R
PE
enunciator, a
FAIL
is indicated.
If the measured value is less than or equal to 1 ohm a
tick is placed next the
R
PE
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
R
ISO
enunciator.
If the Insulation Resistance is greater than or equal to
1 Mohm a tick is placed next to the
R
ISO
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
