5. Press  to select the RCD test-current waveform.
6. At a minimum, connect the leads to L and PE of the system under test, or
plug the mains test cord into the socket under test.
For RCD type B (.) or S-type B (. G) all three test leads
are required.
7. Press and release
turned on, the test starts automatically as soon as the mains voltage is
detected and the required test leads are connected.
The Tester supplies ½x the rated RCD current for 310 ms or 510 ms
(2000 ms in the UK). If the RCD trips, the test terminates. If the RCD does
not trip, the Tester reverses phase and repeats the test. The test
terminates if the RCD Trips.
If the RCD does not trip, the Tester restores the initial phase setting and
supplies 1x the rated RCD current. The RCD should trip and the test
results appear in the primary display.
8. Reset the RCD.
9. The Tester reverses phases and repeats the 1x test. The RCD should trip
and the test results appear in the primary display.
10. Reset the RCD.
11. The Tester restores the initial phase setting and supplies 5x the rated RCD
current for up to 50 ms. The RCD should trip and the test results appear in
the primary display.

current.
•
If the trip time meets the appropriate standard of the RCD, the RCD 
indicator shows. For more information, see RCD Tripping Time table in
Specifications section.
15. Test results are in temporary memory. If you want to store all test results,
