For
precise results
low-ohmic impedances
<
100
£2
should
be measured applying 4
-wire
system. For
this the 4-wire
test
cable with Kelvin clamps
PM
9541 and
the
RCL
adapter
PM
9542
are available.
PM
9541
is
also ideal for
in-circuit testing
of
components.
PM
9542
is
designed
to provide rapid
low impedance connection
to the instrument, whatever the shape
and dimension
of the
component
under
test.
Please
remove
the
two
single test posts,
if
you
use the
double
test
post for
CUT
connection
or
remove
the double
test post
if
you
use the
two
single test posts.
Wrong
insertion of the
plug into the
RCL
meter
is
prevented by unsymmetrical arrangement of the
pins.
About
compensation
of
the zero capacitance chapter 3.4.3. gives
some
information.
When
measuring low-ohmic components
with
PM
9541, the short-circuit inductance
of max.
0.3 juH of
the cable
must
be taken
into
account.
PM
9542
SMD
is
designed
for
measurement
of
SMD
components
(Surface
Mounted
Devices).
The
SMD
test fixture
is
used together with the
RCL
adapter
PM
9542.
For understanding the measurement
circuit
when
applying the
accessories, see
