NOTE
:
Ocassionally
,
during
current
sensor
manufacturing
,
a
slight
separation
occurs
of
the
epoxy
from
the
plastic
shell
.
This
may
amount
to
as
much
as
0.030
M
and
has
no
effect
on
per
-
formance
.
Additionally
,
slight
surface
imperfec
-
tions
are
part
of
the
epoxy
curing
process
and
have
no
effect
on
performance
.
