Now, the leakage current test is carried out:
Checking the limits
UNIMET
®
300ST monitors whether the limits are kept to throughout the test sequence.
If a limit is violated when measuring the PE conductor resistance, the test engineer can decide
whether to abort the test or continue to its completion:
With all the other measurements during which the limit has not been kept to, the test is continued.
However, the test system does not permit any hazardous currents:
Faulty DUTs can exhibit dangerous leakage currents. During all leakage current
measurements, testing is aborted immediately if a measured value >20 mA is
reached. UNIMET

300ST then shows:
