3 Performing ests
Press keys Class I and Class II test buttons together
to s itch on the unit. When the unit is ready the
display ill be as sho n belo .
3.1 esting a Class I Appliance
Visually inspect the appliance as per requirements
of AS/NZS 3760:2010. If the appliance passes a
visual inspection proceed ith the electrical tests.
Plug the earth test lead into the Earth Continuity test
terminal on the PAC3760 plus II end panel.
Plug the appliance into the PAC3760 plus II 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 s itch,
make sure it is in the ON position.
Press the Class I test button to start a Class I test
sequence.
The PAC3760 plus II ill no 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 sho n belo .
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
sho n belo .
If the Earth Continuity test has passed then the unit
ill proceed ith an Insulation test.
Note: he power switch on the appliance under
test must be in the ON position to perform
an insulation test. If no appliance is
