Safety Warning ! When using any electrical appliance SAFETY must always be observed. Testing appliances is no exception and in fact MORE care must be taken to ensure personal safety is met. Although the TnT range of products has been designed to meet stringent requirements, no person can be completely protected against the consequences of the incorrect use of an electrical device. We advise that appliance testing should be conducted by a competent and suitably trained person.

Competent Person ! To ensure that all electrical equipment or devices that are used to perform specific tasks, are inspected and tested and tagged correctly, regulations require that a competent person such as a Licensed Electrician be employed to perform the required tests. A person competent to undertake Inspection and Testing of electrical equipment must therefore have: 1. 2. 3. 4. 5. Knowledge and practical experience of electricity and its hazards.
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.
Technical Information Continued 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’.
Technical Information Continued 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.
Technical Information Continued 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.
Integrated Tests Information SUPPLY MAINS TEST The Supply Mains TEST checks the Polarity & Connectivity of the mains supply by LED’s (see below). This test is also a part of all of the testing functions of this unit. A-N, A-E N-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.
Integrated Tests Information NCNT TEST (No Connection No Test) The TnT appliance tester ensures that the Device Under Test (DUT) 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 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.
Visual Inspection (FIRST TEST) Information THIS TEST IS TO OCCUR BEFORE ANY OTHER TEST IS CARRIED OUT USING ANY OF THE RANGE OF TnT APPLIANCE TESTERS. 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.

Chapter 2 - TnT-el Portable Appliance Test Instructions LEAKAGE TEST Menu 2 The Leakage Test is an alternate method to performing insulation resistance tests. Leakage testing is a major function of the TnT-el & Tnt+ models PLEASE NOTE: A VISUAL INSPECTION MUST BE CARRIED OUT BEFORE ANY OTHER TESTS. [refer to page 13 for more details] This test determines errors of leakage not otherwise detected in a normal insulation test.
Chapter 2 - TnT-el Portable Appliance Test Instructions [continued] LEAKAGE TEST Menu 2 More Information – Leakage Test The Leakage Test allows the user to operate the DUT in normal operation conditions and measure its Operating Leakage current. The displayed parameter is mA: A predefined value for individual class types is programmed into your TnT-el & TnT+ appliance testers. These limits are set according to the AS/NZ3760. Should these values change in future it can be simply altered in firmware.

Chapter 3 – TnT+ Portable Appliance Test Instructions RCD TEST Menu 2 NOTE: Where ANY RCD testing, is to be carried out any circuit that is protected by an RCD in the main switchboard (upstream), it’s most likely to trip this upstream RCD. When performing RCD trip time or trip current tests on any down stream (portable) RCD devices, the RCD in the switchboard will trip faster. This is due to increased upstream levels of leakage current from the additional circuits and devices connected to it.
