30mA X 5.0 = 150mA
These tests should result in no-trip, trip & fast trip times respectively.
F1 - 0 deg
This is the positive half of the mains supply cycle. (50HZ Aust/NZ). Press F1 – The preset
mA test current will then be used in the following test and begin the trip test from the
positive half of the sine wave.
F2 - 180 deg
This is the negative half of the mains cycle, (50HZ Aus/NZ). Press F2 - The preset mA
test will then be used in the following test and begin the trip test in the negative half of the
sine wave.
Performing a Time Test:
The displayed trip time is in milliseconds. 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.
Timed Test 30mA

Settings
RCD Test Options:
F3 – Change to select tested: This allows the user to set the trip current level, 5mA to 500mA. The RCD
type can also be select here depending whether the unit is a type I or type II. See the next section for
explanation. From the options menu press F2 to change the current level and F3 to change the RCD type.
Options:
Set Current
Set RCD Type
Adjusting the current level:
The TnT displays and maintains the last, set trip current value.
If the user wishes to change the value of the trip current the following steps enable the changes:
Press and release F2 from the options section to display test current.
Up - This button raises the trip current in 1mA increments to 500mA. Hold the button and the value will
scroll faster the longer depressed. Once 500mA limit is reached the value will then loop over and start
again from 0mA
