Leak current measurement
for general equipment
The network (human simulated resistance) is
specified separately in each standard, and when
taking measurements a network that is suited to
the standards is needed. The 3156 is pre-engineered
with basic Networks that correspond to each
standard.
IEC standard
[ IEC 60990, others ]
UL standard
[ UL471, UL1310, UL1437, others ]
JIS standard
[ JIS B8561, others ]
The standard numbers that are listed are only examples.
The networks listed below can be used with all applicable
standards.
