2)
the charging current
is
1/3
of the operating current;
thus,
use
of the charger
during operation will not
siginificantly
increase
operating time,
and
3)
the
Jl6
zero will
be
most
stable
on
the higher
sensitivity
ranges
when
operated continuously.
Also, the early
Jl6's
used
a three
pin battery charger plug
that
had
no
strain
relief
and
often
had
the
wires short or break
unbeknownst
to the user.
In
conclusion, recent
Jl6's
are
quite stable
and
should
have
good
correlation
between
individual
units
if
zeroed
and
calibrated
correctly. Older
Jl6's
can
be
brought
up
to date
relatively
easily.

FUSE
FAILURE
MOD
REF:
M51508
As
a
result
of the excessive
number
of
line fuse
failures
caused
by
high
transient
voltages
from
the
AC
line,
a
Metal
Oxide
Varistor (307-0415-00)
has
been
added
to the
power
supply in
parallel
with the spark
gap
A30A2E2010.
To
install
the Varistor, incapsulate
it
in shrink tubing (162-9031-00), lay
it
on
top of
A30A2C2010,
and
solder
the Varistor's leads to the spark
gap
leads.
