3. Press to select the RCD test-current waveform:
• E – AC current to test type AC (standard AC RCD) and type A
(pulse-DC sensitive RCD)
• F – Half-wave current to test type A (pulse-DC sensitive RCD)
• E G – Delayed response to test S-type AC (time delayed AC RCD)
• F G – Delayed response to S-type A (time delayed pulse-DC
sensitive RCD)
1664 FC/1663:
• . – Smooth-DC current to test type B RCD
• . G – Delayed response to S-type B (time delayed smooth-DC
current RCD)
Note
For type F, G, K or R RCDs, choose type A (half-wave current).
The symbol RCD does not consider the short delay of 10 ms
of the G, K and R types. These types need a trip time of at
least 10 ms.
4. Press to select the test current phase, 0 ° or 180 °. RCDs should be
tested with both phase settings, as their response time can vary
significantly.
Note
For RCD type B (.) or S-type B (. G), you must test with
both phase settings.
5. 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.
Note
For RCD type B (.) or S-type B (. G) all three test leads
are required.
