Integrated Tests
Supply Mains Test
[Not available in Battery Mode of TnPB Series]
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
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- 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.
ALL GOOD !!
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.
NCNT Test
(No Connection No Test)
The TnP – 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 TnP appliance tester and that it is switched on. If the device is
not plugged in and the TnP 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
(Done with User Discretion)
With an emphasis in the Standard AS/NZ3760:2010 for carrying out the live testing the TnP - 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 TnP – Series).
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
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.
