Testing a Class II Appliance

•

Visually inspect the appliance and mains cord
for signs of damage.

•

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 DLPT2+ end panel.

•

Plug the appliance into the DLPT2+ front panel
test/mains outlet 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 the CLII test key

•

The display will momentarily show the insulation
test voltage before proceeding with the 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 DLPT2+ will display the
following.
