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 central N-E light is on (red) and you need to conduct load/leakage tests DO NOT CONTINUE. If 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 TnP 3PLM 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), the Mains Supply Test has passed and you can
continue with your testing.
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.
Note: While in Battery mode, all LEDs will be off as no mains connected and supply mains test is not carried out.
No Connection No Test
This test function ensures that the appliance is plugged into the TnP 3PLM and that it is switched on. If the
device is not plugged in and the TnP 3PLM detects that no device is present, and prompts the user to plug in an
appliance to continue the test or press ‘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 - Done with User Discretion
With an emphasis in the Standard AS/NZ3760:2010 for carrying out the live testing the TnP 3PLM 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.
This function is to ensure that correct testing procedures are carried out in accordance with the Standard AS/
NZ3760:2010.
*Optional
Note: When using 3-Phase adaptors the NCNT function will need to be over ridden by pressing the ‘OK’ key prior to the TnP
3PLM 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.
