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 Titan is designed to perform
these tests).
NOTE: The maximum resistive load for the TnT Titan is 10 Amps, and the maximum load for the TnT Titan 20A is 20 Amps
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 - Commonly called Earth Bond Test
Note: Part of normal (Class 1 test) procedure. Use supplied IEC–Alligator Clip lead or optional accessory ‘WCM-Probe kit’.
The TnT Titan conducts earth continuity tests at Approx. 200mA. Continuity tests at higher currents are not
required or recommended on certain equipment as this may cause severe damage or premature failure to the
Device under test (see AS/NZS 3760:2010).
Unique Earth Bond Test Feature
Note: Test time with the new TnT Titan can now be user controlled. This function enables testing personnel to extend the
Earth Bond test time by 30 second increments. This is achieved by momentarily pushing the ENTER button once, during
the test.
The TnT Titan will then add 30 seconds to the test time for ENTER button press.
This feature has been incorporated to provide extra time to achieve an adequate physical connection, or
confirm any possible INTERMITTENT issues. There may be situations where the condition of equipment,
coatings applied, or suspect wiring breaks may alter the earth connection path of the device under test.
Benefit to test personnel is to save time by not having to continually repeat tests in a less than perfect
situation.
3 Phase Testing
Note: 3 Phase Testing requires a three phase adaptor, sold separately. The TnT Titan cannot perform a 3 Phase Leakage
test.
3 Phase appliances can be tested by the TnT Titan appliance testers. As the insulation tests are from Phase to
Earth, only a 500V insulation test is required. This test may be carried out by using the optional adaptor ‘WCM-
3PH-MADP’ [See ‘Optional Accessories’ for details.]
To change the test voltages, when in Main Menu A; Press Enter and F2 together to enter in settings. Select
“Change Insulation Vol” and press enter. Select either 250V or 500V. TnT Titan defaults to 500VDC, and will
revert back to that when restarted.
