During single fault conditions (S.F.C.), referring to the electrical diagram, the
measurements have to be done under the following conditions:
Polarity switch NORM and RVS
GND switch GND open
S1 closed
Test has failed if the measured values are greater than:
N.C. S.F.C
100 pA 500 uA
300 pA (UL requirements)
