RCD test range
Prompts to check and turn on a DUT.
Incorrect connection
Indicates the resistance between L-L (N-N) is less than
10
Ω and polarity is correct.
Open circuit warning
–resistance between L-L (N-N) is
10
Ω or higher at polarity test.
Crossed L-N polarity warning - resistance between
L-N (N-L) is 10
Ω or lower at polarity test.
Short-circuited L-N warning
– resistance between L-N
is 100 kΩ or lower at insulation test. (Extension Lead
Test)
Fault voltage of 50 V or higher is detected at RCD test.
Test result is
“PASS”.
Test result is
“FAIL”.
RCD tripped at fault current detection.
Indicates
the
measured
protective
conductor
resistance is between 0.11 and
0.88 Ω.
