Amprobe MEGATEST-1000 Megohmmeter - Manual (Page 32)

EXAMPLE OF CHECKING THE SEPARATION AMONG ELECTRICAL CIRCUITS
TEST
BETWEEN
THE ACTIVE
PARTS AND
THE EARTH.
Connect a test
lead of the
instrument to
one of the two
conductors of the
secondary circuit
and the other
one to the
equalizing
potential node.
This test is to be
made only on
SELV circuits or
with electrical
separation.
TEST AMONG
