Measuring Insulation
Resistance Time
Characteristics
of
Electro-Mechanical
Components
This
section provides
an example
of measuring
electro-mechanical
components
like
switches
,
connectors
,or
relays.
This example
measures
insulation
resistance
(IR)
time
characteristics
of
opened
switch contacts
using the
continuous
measurement
sequence
mode
,
to
obtain
time
characteristics
.
In
this example
,we
measure
the
insulation
resistance
of
opened
switch
DUT
,
and
print
measurement
data
to
printer
.
W
e
take
a
measurement
every
10
seconds
for
10
minutes
after
a
charge
time
of
60
seconds
.
Warning
Do
NO
T
touch
the
UNKNOWN
terminals or
the electrodes
of
the
accessory
,
when
the
High
V
oltage
indicator is
ON, the
4339B outputs
dangerous
voltage
levels
up
to
1000
Vdc. Before
handling the
4339B or
the
accessory
,
turn
OFF
the
test voltage
pressing
and
conrm
that
the
High
V
oltage
indicator is
OFF.
1.
Connect
the
shunt
connector
and
the
16339A
to
the
4339B
,
and
connect the
printer using
an
GPIB
cable
.
(F
or
the
16339A,
use
the
Alligator
Clip
and
Flat T
able Conguration
as
shown
in
the
16339A
Operation
and
Service
Manual
