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. [. . . ] Connect Earth clip to any exposed metal on DUT (if any, or device can be wrapped in foil or use metal mesh braid [Part No: TnT-ES 500] 4. Press the F2 key and wait for results (Ensure that the DUT's Mains switch is ON). IF THE RESULT OF THE TEST WAS A `PASS' - Tag the DUT with the appropriate tag, including `Next test Due' date and return to service. IF THE RESULT OF THE TEST WAS A `FAIL' - Tag the DUT with a DANGER TAG AND REMOVE THE DUT FROM SERVICE. In some situations if the DUT is labelled with "Surge Protection Fitted" or if it is electronic and fails, conduct a 250V-insulation test.

Lead TEST completes the following sequence as part of its comprehensive testing procedure: [see page 11 for details] 1. CONTINUITY & POLARITY TEST 250VAC Checks continuity & polarity of leads 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' ]: 2. Plug in IEC adaptor lead into IEC socket ( Remove Earth lead if inserted - Please read note below) 3. Plug Male end of Extension lead or Power board into TnT tester DUT socket 4. IF THE RESULT OF THE TEST WAS A `PASS' - Tag the DUT with the appropriate tag, including `Next test Due' date and return to service. IF THE RESULT OF THE TEST WAS A `FAIL' - Tag the DUT with a DANGER TAG AND REMOVE THE DUT FROM SERVICE. Please ensure that the IEC Adaptor & the IEC socket are inserted firmly or it may result in a continuity/polarity fail.

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. 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. 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. [. . . ] This is the time taken for the RCD device to trip once the injected fault current has been applied. The TnT+ injects a true fault current value using a real time compensation calculation of the actual voltage at the time of test. Hence delivering a true and accurate trip current no compensation of voltage fluctuations corrections required. Voltage range 210 ­ 270V ac. As stated above this screen sets the multiplier of the set test current. [. . . ]
