Fluke 1652C User Manual page 37

Potential fields of other earthing installations may influence
the measurement.
Equipment (motors, capacitors) connected downstream of
the RCD may cause considerable extension of the tripping
time.
If the L and N terminals are reversed, the tester will auto-swap them
internally and continue testing. If the tester is configured for UK
operation, testing will halt and you will need to determine why the L
and N are swapped. This condition is indicated by arrows above or
below the terminal indicator symbol ().
Type A and type B RCDs do not have the 1000 mA option available.
To measure RCD tripping time:
1. Turn the rotary switch to the T position.
2. Press  to select the RCD current rating (10, 30, 100, 300, 500, or
1000 mA).
3. Press  to select a test current multiplier (x ½, x 1, x 5, or Auto). Normally
you will use x 1 for this test.
4. Press  to select the RCD test-current waveform:
 – AC current to test type AC (standard AC RCD) and type A
(pulse-DC sensitive RCD)
 – Half-wave current to test type A (pulse-DC sensitive RCD)
  – Delayed response to test S-type AC (time delayed AC RCD)
  – Delayed response to S-type A (time delayed pulse-DC
sensitive RCD)
 – Smooth-DC current to test type B RCD
  – Delayed response to S-type B (time delayed smooth-DC
current RCD)
5. 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 depending on the phase.
For RCD type B () or S-type B ( ), you must test with both
phase settings.
