3.2.8 1700-03 Kelvin Clip Cable
The 1700-03 Kelvin Clip Cable provides a means for
easily making four terminal (Kelvin) connections to
passive components. This cable is especially useful
for testing low impedance devices or devices with
large non-standard terminations, such as electrolytic
capacitors or inductors.

To attach Kelvin Clips as follows to the Digibridge,
first remove any adaptors, cables, etc., if present, from
the DUT port of the instrument. Then connect the bnc
ends of the Kelvin Clips to the Digibridge as follows:

Operation
Zero the Digibridge as instructed in Section 3.1.3
on page 14.
Note that red designates leads that may be "hot."
(When bias is applied, they carry negative voltage
with respect to ground).
If dc bias is used (see paragraph 3.7), notice that the
faces of the Kelvin Clips are labeled "+" and "-" to
indicate bias polarity.
NOTE: It is important to be aware that if DC BIAS
is used, that it is a negative voltage and that it is ap-
plied to the IH lead from the instrument.
For this accessory an additional accuracy (for param-
eters listed) must be added to the standard instrument
accuracy.
Measurement accuracy is very sensitive to connection
geometry. The same connection geometry must be
used for open/short compensation as for connection
to the device under test.
