switch.
In
the
1
(ON)
position
power
is applied
and all
operating voltages
are
applied
to
the
instrument.
In
the 0
(OFF) position
no power
is applied
and no
operating
voltages
are
applied
to
the
instrument.
The
4349B
's
settings
are
held
in backup
memory for
72 hours
after power
is turned
OFF,
and
are
restored
as
the
current
settings
when
power
is
turned
ON again
within the
72 hours
period.
The

T
erminals
These
are
the
terminals
used to
connect
the
test
leads
to
measure
the
DUT
.
The
connector
type
is
triaxial,
which
is congured
as
a
center
conductor
,
an
inner
shield,
and
an
outer
shield.
The
outer
shield,
connected
to
the
ground,
shields
the
test
the
test
signal
from
noise
.
The
inner
shield,
to
which
nothing
should
be
connected,
guards
the
very
small
current
signal,
and
cuts the
leakage
current
of
the
contact
check
signal.
The
center
conductor
,
lead
to
the
test
electrode,
is
the
test
signal
path.
The 4349B
has
four
channels
,
Ch1,
Ch2,
Ch3,
and
Ch4
(If
your
4349B
is
equipped
with
Option
001,
2
Channels
,
there
are
only
two
channels
,
Ch
1
and Ch
2.),
and a
measurement
is
simultaneously
performed
at
each
channel
when
the
4349B
is
triggered
to
make
a
measurement.
The
displayed
channel
is
selected
using
.
Each channel has the respective settings for the following functions:
Test voltage entry
Measurement range (in Hold Range mode)
Limit values for comparator
Caution
DO NOT apply a dc voltage exceeding
6 50 V, or dc current exceeding
6 50 mA
to the UNKNOWN terminals
, or the 4349B
's input circuits will be destroyed.
