(tripping current) or corresponds to the final value, if the RCD
does not trip.
How to perform tripping current measurements
 Select the FI/RCD function by means of the function selector switch.
 Set the sub-function to RCD I.
 Set the testing parameters.
 Connect the test cables to the test object (see figure 5.17).
 Press the "TEST" key to start the measurement.
 Save the measuring result by pressing the "MEM" key (optional).
Figure 5.20: Example of a tripping current measurement
Results displayed:
I ...........tripping current
Uci .......contact voltage at tripping current I or final value, if RCD does not trip
t............tripping time
5.4.4 Automatic test
The automatic RCD test is intended to perform a complete RCD test (tripping time at different
fault currents, tripping current and contact voltage) in a sequence of automatic tests controlled
by the installation tester.

HELP / DISPLAY As soon as measurement is finished, the "HELP" key toggles between
the upper and lower part of the result field.
