■ Combining 2-pole and 4-pole switching
The Model 2001-TCSCAN can combine 2- and 4-pole
switching in various combinations. For example, you might
require 4-pole switching for only two resistors, while the re-
maining resistors could be tested using conventional 2-pole
switching.
Figure 3-5 shows a test configuration using mixed 2-pole and
4-pole switching. Four-pole switching is used only for the
device connected to channels 2 and 7. Five more resistors are
tested using 2-pole switching. In order to use this
configuration, configure the channels for Ω2 and Ω4
functions as appropriate.
