Magnetometer
Probe
is
an
accessory
which
converts
the
Model
428A
or
Model
428B
into
a
magnetometer.
It
is
valuable
in
any

be
made

or
its
magnitude.

(the

it
is
useful
in
a

of
applications,
such
as
meas-

the

DESCRIPTION.
4.
The
accuracy
of
the
Model
3529A
is
better
than
+3%
£0.1
milligauss.
Its
bandwidth
is
from
dc
(non-
varying
fields)
to
80
cps,
allowing
it
to
be
used
in
the
measurement
of
ac
fields
associated
with
power-
line
frequencies.
9.
The
conversion
factor
of
the
Model
3529A
is
1
gauss
=
1
ampere,
that
is,
the
reading
from
the
Model
428A/B
in
amperes
is
directly
equal
to
the
measured
field
strength
in
gauss.
The
component
of
the
field
sensed
is
the
component
which
is
parallel
to
the
cylindrical
axis
of
the
probe,
allowing
the
user
to
eliminate
the
effects
of
extraneous
fields
(such
as
that
of
the
earth,
approximately
500
milli-
gauss)
by
orienting
the
probe.

AS

USE
THIS
READING
AS
A
REFER-

FOR
FUTURE
CALIBRATION.
To
measure
the
earth's
field
in
your
locality
proceed
as
follows:
a,
The
location
for
taking
the
reading
is
important
and
should
be
selected
with
care,
taking
the
following
into
consideration:
(1)
Since
the
reading
is
to
be
the
reference
for
instrument
calibration,
choose
a
place
that
will
always
be
accessible.
(2)
Since
the
presence
of
strong
ac
fields
will
affect
the
reading,
choose
a
location
free
of
power-line
pickup.
(3)
Since
the
presence
of
magnetic
materials
also
wili
affect
the
reading,
choose
a
location
which
either
is
free
of
magnetic
material
such
as
steel
workbenches
and
beams
or
is
one
in
whieh
such
material
will
not
be
added,
taken
away,
or
moved
around.
b.
Plug
Model
3529A
into
Model
428A/B,
and
turn
Model
428
ON,
and
allow
15
minutes
to
warm-up.
c.
Turn
Model
428
OFF
for
30
seconds,
and
then
mechanicall
zero-set

(see
Section
IV
for
details).
d.
Before
any
measurements
are
taken,
the

must
be
centered.
Turn
red
ZERO

control
knob
fully
clockwise
and
mechanically
center
the
large
black
ZERO
control
knob,
This
action
will
set
the
instrument
zero
to
within
+3
milligauss
of
zero
field.
As
the
earth’s
field
is
approximately
500
milligauss,
less
than
1%
error
will
be
introduced.
If
care
is
taken
when
mechanically
setting
the
ZERO
control,
repeatable
readings
within
0.5

should
be
obtained.
For
greater
ease
in

make
a

e.
Point

of

toward
the
south
and
up
(toward
the
south
and
down
in

Extend

at
full

Carefully
orient

(See
paragraphs

f.
Record
the

This
is
the
value
to
use
as

The
earth's

field
does
vary
slightly
but
not
enough
to
be
detectable
on

OPERATION
8.
INTRODUCTION,
9.
The
Model
3529A
measures
the
component
of
the
magnetic
field
which
is
parallel
to
the
axis
of
the
probe.
When
the
meter
reads
up-scale
the
tip
of
the
probe
points
toward
a
north
magnetic
pole
(opposite
to
the
direction
of
the
magnetic
flux).
To
measure
the
earth's
magnetic
field
start
with
the
tip
of
the
probe
pointed
up
(down
in
the
Southern
Hemisphere)
and
toward
the
south
(note
that
the
south
geographical
is
a
north
magnetic
pole).
10.
A
true
reading
of
the
ambient
value
ofthe
earth’s
magnetic
field
will
be
obtained
only
when
all
ferro-
magnetic
materials
(magnitized
or
not)
are
kept
well
away from
the
probe
head.
If
the
probe
is
held
by
a
fixture
be
sure
all
of
the
materials
of
the
fixture
are
non-magnetic
and
clamp
the
handle,
notthe
probe-tip.
When
measurements
must
be
taken
in
a
building
with
a
Steel
framework
keep
as
far
away
from
steel
beams
and
steel-reinforced
walls
or
floors
as
possible.
1l.
MEASURING
STEADY
MAGNETIC
FIELDS.
12.
The
earth's
magnetic
field
is
usually
a
problem
when
endeavoring
to
make
anaccurate
measurement
of
steady
magnetic
fields.
If
the
field
to
be
measured
can
be
turned
off,
the
probe
may
then
be
oriented
to
give
a
zero
reading
on
the
meter.
When
the
field
to
be
measured
is
turned
on
the
probe
will
indicate
the
component
of
the
field
in
the
direction
of
the
probe.
If
this
is
the
direction
in
which
it
is
desired
to
measure,
or
if
merely
maximizing
the
field
is
desired,
this
procedure
is
satisfactory.
However,
if
the
field
must
be
measured
in
some
other
direction,
other
techniques
must
be
used
(see
following
paragraphs).
13.
The
earth’s
magnetic
field
can
be
cancelled
out
at
the
point
of
measurement
by
building
a
pair
of
Helmholtz
coils
around
the
probe.
Orient
the
coil
axis
parallel
to
the
earth’s
field
and
run
current
through
the
Helmholtz
coils
in
the
proper
direction
and
magnitude
to
zero
the
meter.
Then
insert
the
'
field
to
be
measured
and
measure
in
the
normal
way.
The
reading
of
the
meter
in
this
case
will
be
only
the
desired
field.
14.
If
the
field
to
be
measured
cannot
be
turned
off,
other
techniques
must
be
used.
If
the
device
generat-
ing
the
field
can
be
oriented,set
the
device
to
a
position
where
you
can
get
maximum
reading.
Record
the
reading
and
then
rotate
the
device
about
an
axis
on
a
lne
between
the
object
and
the
probe.
Rotate
for
minimum
reading
on
the
meter,
and
record
this
reading.
The
component
of
the
field
from
the
device
in
the
direction
of
the
probe
axis
is
one-half
of
the
difference
between
the
maximum
and
minimum
read-
ings.
The
external
field
of
a
magnet
may
be
measured
by
this
method,

MEASUREMENTS
OF
ALTERNATING
FIELDS.
16.
Measurements
of
alternating
fields
can
be
per-
formed
only
by
measuring
the
output
of
the
front-
panel
OUTPUT
jack
with
an
ac
voltmeter
or
an
oscilloscope
since
the
meter
on
the
instrument
reads
only
the
steady-state
value
of
the
magnetic
field.
The
OUTPUT
jack
is
a
de
coupled
output
that
gives
one
volt
for
a
full-scale
reading
of
the
field
as
selected
by
the
RANGE
switch.
CAUTION
-.
The
signal
resulting
from
the
steady-state
value
of
the
magnetic
field
plus
the
peak
value
of
the
ac
field
must
not
overdrive
the
ampli-
fliers
in
the
instrument.
To
check
the
steady
field
condition,
observe
the
meter;
if
the
needle
is
offscale
the
amplifier
may
be
overdriven.
To
check
the
ac
pick-up,
con-
nect
an
oscilloscope
to
the
front
panel
OUT-
PUT
jack
and
observe
the
waveform
for
clipping.
1f
either
condition
is
observed,
the
amplifier
is
saturating
and
the
instrument
must
be
switched
to
a
higher
range
to
give
a
true
reading.
Because
of
the
magnitude
of
the
earth’s
field,
generally
ac
measurements
must
be
made
onthe
1
AMP
or
greater
range.

21.
PROBE,
The
Model
3529A
is
a
simple
device,
consisting
of
two
drive
coils,
wound
around
forms
containing
core
material,
and
an
output
coil
wound
around
both
drive
coils.
In
general,
probably
the
only
troubleshooting

that
will
be

is

the

as
follows
to
obtain
best
accuracy
and
mechanical
stability:
a.
Allow

minutes;
this
allows
meter

TROUBLESHOOTING.
25,
If
you
have

type
of

such
as
the

isolate
the

to
either
the

or
to
the
probe,
by
substitution.
If
the
trouble
is
in
the
instrument
follow
the
trouble-
Shooting

given
in
paragraph
29.
If
the
trouble
appears
to
be
in
the

see
the
next
paragraph.
26.
PROBE.
27.
If
the
trouble
appears
to
be
in
the
probe,
discon-
nect
the
probe
from
the
Model
428A/B,
and
measure
the
resistance
across
each
of
the
two
windings.
Only
a
few
ohms
should
be
measured
across
either
winding
1-2
or
winding
3-4
(terminalnumbers
appear
adjacent
to
the
pins,
on
the
face
of
the
probe
connector).
There
shouid
be
no
conductivity
between
winding
1-2
and
winding
3-4,
a.
If
an
examination
of
the
connector
indicates
the
connector
is
defective,
note
how
the
wires
are
con-
nected,
and
then
replace
the
connector.
This
con-
nector
is
identical
to
the
one
used
onthe
Model
428A/B.
b.
If
the
wires
inside
the
probe
or
cable
are
de-
fective,
probably
the
entire
assembiy
will
have
to
be
repaced
as
the
inside
of
the
probe
is
filled
with
Silastic
compound
to
protect
the
leads
from
mechanical
damage.

MILLIAMMETER,
29.
In
general,
instrument
troubleshooting
and
main-
tenance
techniques
are
the
same
whether
the
probe
used
in
the
428A-21A
current
probe
or
the
Model
3529A
magnetometer
probe.
However,
wherever
the
Page

technique
requires
current
through
the
probe,
procedures
given
in
the
Model
428A/B
manuals
will
require
some
modification.
Such
modifications
are
discussed
in
the
following
paragraphs.
30,
CALIBRATION,
Instead
of
the
accuracy
check
procedures
given
in
the

(Model

table
4-2;
Model

and/or
step

check
instrument
calibration
by
re-measuring
the
earth’s
magnetic
field
strength,
and
comparing
the
reading
obtained
with
the
reference
reading
made
as
instructed
in

If
the
readings
are
not
the

follow
the

the
instru-

SIGNAL
SOURCE.
Some
of
the
techniques
des-
cribed
in
the
paragraphs
listed
below
require
that
there
be
an
input
signal.
A
suitable
ac
input
may
be
obtained
by
placing
the
magnetometer
probe
near
a
power-supply
transformer.
With
such
an
input,
the
following
procedures
can
be
used.

proceed
as

See
step

table

(1)
Obtain
a

as

to
an

which

except
for

Model
428A.
Since
the

does
not
have
an

the
procedure
is
somewhat
more
complieated
than
that
specified
for

measuring
the

involves
disconnecting
