Step 5 and
Step 6
Individual steps in RCD autotest
The test passes if tested RCD:
- Does not trip out at ½I
N
tests, and
- Trips inside predefined time limits at I
N
, and 5I
N
tests.
Displayed results:
Main result ............. last measured results
Sub-results ............ all results are displayed as sub-results
Ul-pe ...................... voltage UL-PE
Notes:
Consider any displayed warning before starting measurement!
For DUTs with integrated RCD the housing must be opened to access the RCD’s L
output terminal (this should only be performed by a competent engineer).
Mains voltage is applied to the RCD under test. Do not touch the equipment under
test or the test leads during the test!
Testing B-type (P)RCD can only be performed on hardware release 2.0 and up and
firmware release 1.24 and up.
