fuse
is
located behind
the front-panel
MA
INPUT
ter-
minal,
and
is
accessed by
turning (ccw) and

Overrange
Indication
2-20.
The
front panel
display,
in
addition
to
providing
a
measurement
reading,
is
designed to
serve as
an overrange
indicator.
When
the
full scale capability of
the selected
range
for
any
function
is
exceeded,
the display
will blink
while indicating
a
18888
reading.
The
presence of an
overrange indication
does not
necessarily
mean
that the
instrument
is
being exposed
to
a
damaging
input condition.

8600A
will select
the lowest
range that
will
display the value of
the input
signal
without
causing an overrange
indication.
Autoranging

of
the individual
range pushbuttons
is
