All
signal
wiring
in
the
Type
561A
is
color
coded
to
moke
circuit
tracing
easier
In
addition,
all
regulated
power
supply
leads
are
color coded
to
follow
the standard
EIA
code
The
first
color
(widest
stripe)
indicates
the
first
number
of
the
voltage,
The
second
color indicates
the
second
number
ond
the
third
color (smallest
sttipel
indicates
the
multiplier,
The
voltage
is positive
if
the
main
color
of
the
wire
is
white
and negative
if
the main
color
of
the
wire is
dark,
Four
colors
would
be
required
to
indicate
all
the
digits
plus
a
multiplier
for
the
4-125-
volt
leads.
To
avoid
this,
the
|
125-volt leods
are
coded
as
+120; that
is,
brown,
red,
brown
on
o
white
base.
A
—
100-volt
lead
is
coded
brown,
black,
brown
on
a
gray
base
while
+300-volt
leads
are
coded
orange, black,
brown
on
white,
The
switch
wafers
shown
on
the
Calibrator
diagram
are
coded
to
indicate
the
position
of
the
wafer
on
the
switch.
Wafers
are
numbered
from
the
front
of
the
switch
to
the
rear.
The
letters
F and
R
indicate
whether
the front
or
rear of
the
wafer
is
used
to
perform
the
particular
switch
ing
function.
