GENERAL DESCRIPTION
MODELS 61OB, 610B~ ELECTROMETERS
1-6.
ACCESSORIES.
a.
Three
accessory
probes,
fully
described
in Section
5, facilitate
measurements
end
extend
the Electrometer's
voltage
range
to 30 kilovolts.
b.
Model
6104 Test
Shield
is
suitable
for
resistance
measurements
with
either
2 or 3-
terminal
guarded
connections,
as well
as voltage
and current
tests.
c.
Model
6105 Resistivity
Adapter
ts a guarded
test
fixture
for
measuring
volume
and
surface
resistivitirs
of materials
when used with
the Model
6108 and the
Keithley
Node1
240A High
Voltage
Supply.
d.
Models
2501 and 2503 Static
Detector
Probes
are capacitive
voltage
dividers
with
a
10,OOO:l
ratio,
when used with
the
probe
3/B inch
from
the
charged
surface.
e.
Model
6106 Electrometer
Connection
Kit
contains
a group
of
the mwt
useful
leads
and adapters
for
electrometer
measurements.
f.
Model
6107 pH Electrode
Adapter
has a 2-Eoot
cable
and coaxial
caxxector
and accepts
a Beckman and Coleman
(B-C)
or a Leeds
and Northrup
(L &N)
connector.
The Adapter
allows
accurate
and convenient
pH potential
measurements
with
the Model
6lOB.
g.
Model
370 Recorder
is uniquely
compatible
with
the Model
610B es well
es other
Keithley
microvoltmeters,
electrometers
and picoarmneters.
The recorder
is
a high
quality
economical
instrument
that
maximizes
the
performance
of
the Model
6108 and many other
Keithley
instruments,
even
in the most critical
applications.

ped with
all
components
in place.
The shipping
cartnn
contains
the
Instruction
Manual
and
mating
plugs
for
