Note: Before operating, ensure the equipment firmly secured and is free from any possibility of causing injury or
damage. This function turns the appliance on any, rotating devices have clearance from body or object. Appliances will
jump of benches if not secured properly.|
Caution: This test turns the Device Under Test (DUT) ON. The power / leakage test can handle up to 10 Amp (Resistive) Load
MAX. Exceeding this value will blow the external M205 ceramic fuse. Care should be taken when testing inductive loads (ie AC
motors) with large start up currents. To stop operation press and hold the Return/Enter key at any time. The unit will power
down after 20 seconds as default.
If 10A HBC fuse is blown the appliance will not operate in Power test or Leakage test modes. Replace fuse only with M20 10A
HBC fuses. Any other fuse voids warranty and manufacturers design. Do not open TnT case as there are no serviceable parts
inside.
Leakage Test
Refer to TnT-el
RCD Test - Menu 2
Please 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. The fixed RCD‟s can also have better connectivity, sensitivity and
mechanical mechanisms.
To avoid tripping large areas in the work place monitored by the switchboard RCD it is suggested that an RCD isolation
transformer be used. (TnT-ISOT) These are designed specifically for the purposes of field RCD tripping.
DO NOT use these Transformers for any other purpose.

To perform RCD tests the TnT+ supply lead needs to be plugged in to the RCD device to be trip tested. For tripping
switchboard mounted (Fixed) RCDs Plug TnT+ into GPO marked RCD protected or if known to be protected circuit. (Diagram 2)
If testing portable RCD devices on power boards or extension leads plug TnT+ into power board or lead (recommend Isolation
transformer) Diagram 1
