The
lamp
should
be slightly recessed
within
the pen
case
so
that it
is protected
and
yet can still
be seen. The
two flexible
test leads
(red for positive
and black
for ground)
can be
brought out
of
the
probe beside
the lamp.
These leads
can
be
a
couple
of feet long if
desired (18"
is
about
ideal)
and
should be
terminated
with
small
alligator
clips.
To
