optional accessory for
PM 9542
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 figs.
