You can also use the tester to perform the RCD tripping time test in Auto mode, which
makes it easier for one person to perform the test.
Note: When measuring trip time for any type of RCD, the tester first does a pretest to
determine if the actual test will cause a fault voltage exceeding the limit (25 or 50 V).
To avoid having an inaccurate trip time for S type (time delay) RCDs, a 30 second delay is
activated between the pretest and the actual test. This RCD type needs a delay because it
contains RC circuits that are required to settle before applying the full test.
WWarning
• Leakage currents in the circuit following the residual current protection device may
influence measurements.
• The displayed fault voltage relates to the rated residual current of the RCD.
• 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.
Note: 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 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
2. Press F1 to select the RCD current rating (10, 30, 100, 300, 500, or 1000 mA).
3. Press F2 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 F3 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 F4 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
