MODEL 6104 TEST SHIELD.
a.
The Model
6104 is useful
for
making
guarded
measurements
or to avoid
pick-up
problems.
For resistance
measurements,
it
can be used with
either
two-teminal
or three-terminal
connections.
The Model
6104 is also
suitable
for
voltage
and
current
tests.
b.
2-Terminal
Operation.
1.
Connect
the
high-impedance
side
of the
test
sample
to the
Model
6104
INPUT terminal.
Connect
the
low-impedance
side
to either
black
jack
marked
GROUND, whichever
is more convenient.
2.
Lock the
enclosute
and connect
the
mdel
6104 bnc-type
receptacle
to the

6LOB INPUT Receptacle.
Use a short
coaxial
cable
lead.
Operate
the
Electrometer
as explained
in
Section
2.

3-Terminal
Operation.
1.
For guarded
measurements,
make the
connections
as above
with
some
additional
steps.

either
terminal
marked
EXTBBNAL SOURCE to the
test
sample
at
its
high-impedance
side.
Lock the
enclosure
and connect
the Model
6104 to
the
Electrometer.
4.
Connect
the
external
power
source
to the l@del
6104 banana

MODEL 6105 RESISTIVITY
ADAPTER.
a.
The Model
6105 is
a guarded
test
fixture
for
measuring
resistivities
of
materials
in conjunction
with
the Node1 6LOB and the Model
240A Regulated
High
;Jl:"~l;~gPlY.
The complete
system
directly
measures
volume
resistivities
up
ohm-cm and surface
resfstivities
up to 5 x 1018 ohms,
in accordance
with
the
procedures
of the
American
Society
for
Testing
and Materials.
