Technical Information
CLASS 1 (Earthed Appliance) CONSTRUCTION
(Single basic insulated and protectively earthed equipment)
This type of product design provides two safety barriers between all live conductors at
dangerous voltages and the equipment user.
The provision of basic insulation between exposed metal parts and live parts is the first
barrier to provide basic protection against electric shock.
The second safety barrier is by the connection of exposed (accessible) conductive (metal)
parts to the protective earthing conductor (earth wire) in the fixed wiring of the
device/Installation.
The protective earthing terminal of the equipment must be marked with the word "earth" or
the symbol "E" or the symbol for Earth Terminal or Protective
Conductor Terminal.
To perform this test a continuous earth loop must be made between the exposed
conductive material (metal) and the TnT appliance tester. This is done by means of
connecting the earth lead with the crocodile clip/probe attached to a GOOD earth point
(paint & coatings will not provide effective connections) and the DUT (Device Under Test)
plugged into the TnT appliance testers’ DUT socket. [as shown in the above picture]. The
Maximum allowable limit is 1.0Ω(ohm).

CLASS 2 (Double Insulated) CONSTRUCTION
(Double insulated equipment)
This method of construction employs two safety barriers comprising two layers of
insulation between dangerous voltages and the user of the equipment.
The first layer of insulation is formed around the live conductor and is termed ‘the
Functional Insulation’.
The second layer of insulation is termed ‘the Supplementary Insulation’. In Class II
equipment, protection against electric shock does not rely on
basic insulation only, but has additional supplementary
insulation such as double insulation or reinforced insulation
provided, there being no reliance on precautions in the fixed
wiring of installation.
Class II equipment is marked with the words "DOUBLE
INSULATION" or the symbol
For double insulated under Safety Symbols:
Note 1 – Double Insulation is insulation comprising both basic and supplementary
insulation.
Note 2 – Reinforced Insulation is a single insulation system with a degree of protection
against electric shock, which is equivalent to double insulation.

Testing of Electrical Equipment
Many testing personnel have some reservations in testing sensitive, electronic equipment
using a 500V DC insulation test. There is a perceived fear of causing internal damage
from over voltage. With the introduction on the TnT Range of appliance testers, these
concerns are alleviated.
The TnT Range of electrical portable appliance testers are safe to test electronic
equipment as the tests are carried from Active-Neutral (shorted by a relay inside the
tester) to Earth. No dangerous voltages pass through in this mode to the internal
components of the DUT (Device Under Test). If these tests are done using an Insulation
Tester only and the user tests Active to Neutral, this would be a cause of potential
damage, this is why the TnT product range is far safer to use.
Some changes may be required in certain configurations where fitted surge protection
devices (MOV's) in the DUT may cause a failed test result. Applying 500V in this these
situations can cause the surge protection devices to trip, therefore conducting the applied
voltage to earth, thus showing a failure of insulation. In these instances the test voltage
should be changed to 250V then retest. If DUT still fails, check with the DUT Operators
Manual or an electrician. [Refer to page 13 for details - ‘Double Insulation Test’
250/500VDC to change test voltage].
Under these circumstances, it would be difficult for any damage to occur to either the
surge protection device or the DUT, as there is insufficient current generated by the TnT-el
appliance tester.
Leakage Test:
If there are any doubts with insulation testing of the equipment, the standard
(AS/NZ3760 since 2001) allows for an alternative test method. A Leakage Test can be
performed instead. (The TnT-el & TnT+ models are designed to perform these tests).
NOTE: 10Amps MAXIMUM Resistive Load only (Standard TnT-el & TnT+ units).
A Leakage Test applies power to the Device Under Test (DUT) and measures the
imbalance of leakage current from the DUT between the active and neutral conductors.
The leakage is tested to the limits specified in the standard and a Pass/Fail result as well
as a digital reading is provided to ensure that the user gains as much information as
necessary.
Earth Continuity Test:
The TnT-el conducts earth continuity tests at Approx 200mA. Continuity tests at
higher currents are not required and are not recommended on certain
equipment as this can cause severe damage or premature failure to the DUT (as per
AS/NZ3760).

Testing of Electrical Equipment
3 Phase Testing:
3 Phase appliances can be tested by the TnT, TnT-el, TnT+ or the TnT-3PL appliance
tester. This test is carried out by using the adaptor connection sockets. As the insulation
tests are from Phase to Earth, only a 500V insulation test is required. These adaptors can
be made by your electrician or purchased as an accessory. [See ‘Optional Accessories’ on
page 18 for details - when ordering please state plug configuration of 3 phase plug. E.G.
5 pin Clipsal 56 series 20A].
CAUTION: Ensure that these adaptors are used only for appliance testing.
To Change Test Voltage
(250/500 VDC Select - To Change the Insulation Test Voltage on all models)
Procedure:
Step 1: Hold down the Return/Enter Key
Step 2:
Press the F2 Key
(F2 function – Note screen flashes)
Step 3:
For 250v – Press the F3 Key
For 500v – Press the Return/Enter Key
Finish: The display will confirm the change and return to the
Main Menu automatically. The desired voltage has
now been selected.
TO CHANGE VOLTAGE BACK, REFER TO STEP 1.
Please Note:
1. In earlier models the Return/Enter Key may need to be pressed 3 times to change
Voltages.
2. The TnT will automatically default to 500v when restarted.

SUPPLY MAINS TEST
A-N, A-E
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 TnT-el 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 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.

Information
NCNT TEST
(No Connection No Test)
This test function ensures that the Device Under Test (DUT) is plugged into the TnT
appliance tester and that it is switched on.
If the DUT is not plugged in and the TnT appliance tester detects that no DUT is present,
plug in the DUT to continue the test. Confirm or ‘QUIT’ to return to the main menu.
If for some reason the NCNT circuit does not detect the DUT but it is actually plugged in
and turned on, the operator will need to override the TnT appliance tester to continue the
test.
To do this - press the F3 Key.
With an emphasis in the standard AS/NZ3760 for carrying out the live testing the TnT
appliance tester will indicate for you to check if the DUT is plugged in and switched on. If
the DUT 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 (TnT-el & TnT+
appliance tester models only).
This function is to ensure that correct testing procedures are carried out in accordance
with the Standard AS/NZ3760.
TO NOTE:
i. 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 require manual over
ride also. In some instances holding the ‘ON’ button of the DUT will enable the
NCNT function to work normally.
The TnT appliance tester ensures that the De
vice Under Test (DUT) is
plugged in and switched on. This test is also a part of all of the testing
functions of this unit.
Page 13
Visual Inspection (FIRST TEST)
Information
In regard to the Device Under Test (DUT), please ensure that;
1. There is no damage or component defect to the accessories, plugs, outlet sockets
or connectors (physical).
2. There are no cracks &/or abrasions.
3. There are no exposed inner cores or conductors (flexible) and that the supply cords
are not twisted or distorted.
4. Any Fuse / Over load protection components (if fitted) are checked.
5. All labels, markings and warning indicators (of the maximum load to be connected
to the device) are legible and intact.
6. The insulation is not damaged in any way i.e. melted, cuts or abrasions. There are
no iron filings in the insulation. There is no insulation tape on the lead.
7. Any flexible cords and/or leads are effectively anchored (glands and grommets
intact).
8. All covers/guard are in place and secure as intended by the supplier/manufacturer.
9. All safety devices and systems are in good working order. (ie. overload latches &
buttons).
10.No dust &/or dirt obstructs any exhausts or ventilation outlets.
11.All controls are working properly and are secure and aligned.
Important:
IF RESULT IS A FAIL
If a Device Under Test (DUT) fails any
of the above, it should be deemed to have
FAILED the Visual Test, and therefore no other tests need be performed. If this is
the case the DUT should be tagged with a danger tag and removed from service.
It is recommended by the manufacturer a
nd distributor of this product that if a
DUT has failed a test it SHOULD NOT BE RETURNED TO SERVICE.
To do so
would be considered unsafe.
THIS TEST IS TO OCCUR BEFORE ANY OTHER TEST
IS CARRIED OUT USING ANY OF THE RANGE OF
TnT APPLIANCE TESTERS.

LEAKAGE TEST
Menu 2
This test determines errors of leakage not otherwise detected in a normal insulation test.
If there are any doubts with insulation testing of the equipment, the Standard (AS/NZS
3760 since 2001) allows for a leakage test to be carried out instead. The TnT-el & TnT+
appliance testers have been designed to perform these tests. The Leakage Test applies
power to the Device Under Test (DUT) and measures any imbalance or leakage current.
The leakage is tested to the limits of the class types specified in the Standard AS/NZS
3760 ie. Class 1 = > 5mA as Fail.
The Limit of imbalance measured on the TnT-el appliance tester will read well in excess of
the limits set in mA. However, should the supply circuit be protected by an RCD this
device will trip any where between 10 to 30mA and trip the mains supply switch OFF.
PROCEDURE:
1. Complete a VISUAL INSPECTION on the DUT (Device Under Test)
[refer to page 13 for details – ‘Visual Inspection’].
IF THE DUT PASSED THE ‘VISUAL INSPECTION’, CONTINUE WITH THE FOLLOWING
INSTRUCTIONS [if not, refer to page 13 ’IF RESULT IS A FAIL’]:
