do not contribute additional errors due to self or mutual inductance
between the individual leads.

Contacts
This paragraph gives general notes and techniques for using the
four-terminal pair conguration eciently.To realize accurate
measurements using the four-terminal pair measurement technique,
the following are required to make measurement contacts (the
number labels in the following description corresp onds to the
numbers in Figure 6-7).
1. The signal path b etween the HP 4284A and DUT should b e as
short as p ossible.
2. To construct the four-terminal pair measurement circuit
conguration, the outer shields of H
CUR
and H
POT
,L
CUR
and
L
POT
terminals must b e resp ectively connected together at the
point as near as p ossible to the p oin
t at which the DUT will
connected.
3. Keep connections b etween the p oint at which the shielding ends
and DUT as short as p ossible.

The following paragraphs will giveyou some techniques for using the
four-terminal pair conguration eectively and eciently.
