• Touch Leakage Test

Test
The Tester performs an initial low voltage test to establish that the
appliance can be safely powered.
Warning
It is important that the user verifies that an appliance
with moving parts (e.g. an electric drill) is safely
mounted to allow movement without causing damage to
equipment or personnel.
If the potential load current is too high, a warning message appears,
allowing the user to continue. If a Live to Neutral short exists, this
message will appear, and if tests are continued the 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 a safety test to verify that internal
relays are properly set before applying full mains supply to the
appliance.
Power to the appliance will remain until the Red Button is pressed.
This allows the user to switch between the three powered tests
without removing power from the appliance.
Leakage Test
Warning
Mains voltage applied to appliance
The 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 away from the
