Differential Leakage Test
27
If the potential load current is too high, a warning message appears,
allowing the user to continue. This message will be displayed if a
Live to Neutral short exists, and if tests are continued the tester’s
fuses will blow.
If the potential load current is low, a warning message appears to
allow the user to check that the appliance is switched on, and all
fuses are intact.
The Tester also performs an internal safety test to verify that internal
relays are properly set before applying full mains supply to the
appliance.

Test Description
The Differential Leakage Test shows the current being lost through
Leakage as the difference in the currents flowing in the Live and the
Neutral conductors. This difference is the total leakage current from
the appliance, and is generally equivalent to the current flow through
the earth lead of the appliance. The test result is displayed in
milliamps (mA).
