Class I equipment is earthed whereas Class II equipment is not earthed (double-insulated),
usually denoted by the symbol

The instrument can be connected directly to a 240V supply using the 13Amp plug fitted on
the supply lead or to a 110V supply, using the adapter supplied. On power up the EasyPAT
monitors the supply voltage, adjusts its measurement circuits and selects the correct test socket
accordingly. The display indicates the supply voltage on which tests will be carried out.
Appliances to be tested should be connected into the appropriate test socket and should be
compatible with the supply voltage to the instrument. If the appliance has an on/off switch, it
should be set to the on position to ensure that the appliance is fully tested.
1)
EARTH / CONTINUITY (8 AND 25Amps)
For this test a voltage of 6V a.c. is applied between the earth pin of the plug of the
appliance being tested and its exposed metal work, via the wander earth lead. The
magnitude of the test current is reduced to 8A by a limiting resistor selected by the
three position rocker switch. The high current applied in this test verifies that the
protective earth path will carry the fault current in the event of an insulation breakdown
within the appliance.
2)
EARTH / CONTINUITY (100m A)
The test is similar to that described in (1) except that a constant current of 100m A
d.c. is applied. This reduced current is required to test I.T equipment whose earth
path could be damaged by the higher currents.

CLEANING
Do not use volatile liquids such as thinner or benzene to clean the tester. Wipe the tester with
a soft, dry cloth or moisten the cloth with a neutral non abrasive detergent and wring the cloth
out thoroughly before wiping over the surface. Ensure that all traces of moisture have evaporated
before using the tester.
