When making connections:
•
Connect force leads to binding posts 4, 5, and 6
•
Connect sense leads to binding posts 1, 2, and 3
These pins are connected internally to each other (binding post 1 to post 4, 2 to 5, and 3 to 6).
However, posts 4, 5, and 6 have a shorter path to the socket than posts 1, 2, and 3, which results in a
lower resistance path. This is particularly important for high-current applications.
When testing axial-lead devices, note that posts 1 and 3 put the sense leads closer to the device
under test. This reduces measurement error due to lead resistance.

Two 8010-DTB high power socket module test boards are installed in the Model 8010. The Model
8010 is also shipped with an 8010-CTB Customizable Test Board, which allows you to add your own
connections.
In addition, you can purchase the 8010-DTB-220 Device Test Board for use with three-terminal
TO-220 or TO-247 devices. You can also purchase replacement 8010-DTB and 8010-CTB boards.
Installing a device in the axial posts
This section discusses how to install devices in the axial terminal posts on the 8010-DTB or 8010-
DTB-220 Device Test Board.
To install a device in the axial posts:
1. Insert the device in the axial posts.
2. Insert the insulating plug in the TO socket terminals if needed. See
page 3-6) for detail.
See
Axial-lead device high current test
(on page 5-1) for an example.
