Comment/Remark
Mains internal resistance,
Contact electrode PE (21) is touched:
Loop resistance,
PE error, PE not connected.
RCD test
The phase present at test leads L/L1 or N/L2
Mains internal
Contact electrode PE (21) is touched:
resistance,
PE error, PE carries a dangerous voltage.
Loop resistance,
RCD Test
Mains internal
Socket L/L1-N/L2 of test leads or mains plug are trans
resistance,
posed. Turn shockproof plug.
Loop resistance,
For exact evaluation touch contact electrode (21)!
RCD test
Mains internal
Socket error:
resistance,
A contact voltage exceeding 25 V is present between N
Loop resistance,
and PE. It is possible that
RCD test
the impedance of N and/or PE is too high. For exact eval-
uation touch contact electrode (21)!
Mains internal
Socket error:
resistance,
The voltage between measurement socket L and N is
Loop resistance,
not within the specified range. It is possible that the im
RCD test
pedance of L or N conductor is too high.
Loop Resistance
An integrated fuse is defective and must be replaced.
Mains internal resistance
RCD test
Loop resistance,
During loop or mains internal resistance test
Circuit breaker.
If the RCD trips during mains internal resistance test,
then the neutral conductor (N) and the protective earth
conductor (PE) are transposed!
RCD test
The test result is correct. The RCD has correctly tripped.
RCD test
The trip time test has been interrupted because the con-
tact voltage has exceeded the limit value of 25 V.
