This instrument has been designed to be used in a clean dry environment. Do not use the
instrument outdoors in wet conditions.
3)
INSULATION
500V d.c. is applied between the appliance phase and neutral joined together
and earth to ensure that this insulation is at an acceptable level.
4)
RUN / CURRENT
The appliance under test is operated at the nominal supply voltage and the current to
it is monitored. Care should be taken to ensure that there is no mechanical hazard
with this test and that the wander earth lead is disconnected.
5)
RUN LEAKAGE
This test is similar to that described in (4) except that the current flow in the
earth lead is monitored to check that no potentially hazardous, voltage induced,
earth leakage paths are created when the appliance is operating.
6)
FLASH
This is an optional test that may be omitted. On Class I appliances 1.5kV a.c. is
applied between the phase and neutral joined together and earth. The flash
probe is not required for Class I appliances but on Class II appliances 3kV a.c.
is applied between the phase and neutral joined together and the tip of the flash
gun which is touched onto exposed appliance metalwork. This test is a further
verification that functional and supplementary insulation levels have not
deteriorated.
Though all tests can be performed in any desired sequence, it is recommended
that the Continuity test is always carried out first on Class I appliances and if
this results in a fail no further tests should be carried out on the appliance until
the fault in its protective earthing has been rectified.
For both Class I and Class II appliances, it is recommended that an Insulation
test is successfully carried out before attempting a Run test or a Flash Test.
The results of the tests are displayed on a high contrast 2½ digit LCD which
also indicates the parameter being tested,(

supply voltage which can be either (110 or 240V). See Fig.2.
