The Test Sequence

3: Insulation Test
If selected in the test settings, the Insulation Test will be performed.
The test applies 250V or 500V to Live & Neutral with respect to
Earth.
The protective insulation between Live / Neutral and Earth is then
measured and displayed in M
Ω.
If testing a Double Insulated product, use the Flash probe and apply
it to a suitable test point on the product under test.
4: Short to Case
The Short Line to Case test will be performed automatically and will
display the fault current that would have resulted from applying the
full mains voltage to the product.
This test is designed to avoid the risk of powering up a product that
has a severely damaged insulation. A safe voltage level of 40Vrms
is applied to both Live and Neutral conductors and the resulting
current to Earth is measured.
If this test fails, testing on the product must not continue until
the fault has been rectified.
5: Flash Test
WARNING - The voltage output during this test is potentially
lethal.
Do not test if you are in any doubt about the
safety of the test facility.
Do not test if the Earth Bond test has not been
successfully performed if testing a metal cased
product.
NEVER touch the product during any of the
tests.
