Supply Mains Test
The Supply Mains Test checks the polarity and connectivity of the mains supply by LED's. This test is also a
part of all the testing functions of this unit.
If the N-E (red) light is on and you need to conduct load/leakage tests
you are carrying out standard Insulation and Earth Bond tests, it is generally safe to
continue. This light will glow if a voltage difference lies between the neutral and the earth, or if
no earth is connected to the TnT- Series supply. (If working with a generator or inverter, this is
most likely to occur and you may need to consult an electrician before proceeding).
If both the A-E & A-N (green) lights are on but not the N-E (red), mains supply test is ok,
continue to test.
If both of the N-E (red) & A-E (green) lights are on, consult an Electrician, as there is a fault
with the Mains Supply.
NCNT Test
(No Connection No Test)
The TnT – Series appliance testers ensure that the appliance is plugged in and switched on. This test is also a
part of all of the testing functions of this unit.
This test function ensures that the appliance is plugged into the TnT appliance tester and that it is switched on. If
the device is not plugged in and the TnT appliance tester detects that no device is present, plug in to continue the
test or confirm 'QUIT' to return to the main menu.
If for some reason the NCNT circuit does not detect the device but it is actually plugged in and turned on, the
operator will need to override the NCNT function.
To do this Over Ride Press F3
With an emphasis in the Standard AS/NZ3760 for carrying out the live testing the TnT - Series appliance testers
will indicate for you to check if the device is plugged in and switched on. If the device is not plugged in and/or
recognised, it may require a live test therefore making it necessary for the operator to carry out a full functional
Leakage Test (Available on all models of TnT – Series).
This function is to ensure that correct testing procedures are carried out in accordance with the Standard
AS/NZ3760.
*Optional
Note: When using 3-Phase adaptors the NCNT function will need to be over ridden by pressing the 'OK' key prior
to the TnT appliance tester performing the assigned test. Some single Phase appliances controlled by contactors
will also require manual over ride. In some instances holding the 'ON' button will enable the NCNT function to work
normally.
