Two-wire resistance tests
The figure below shows a typical setup for making 2-wire resistance measurements. The following
figure shows an equivalent circuit. The 2000-SCAN provides the switching function, while the
resistance measurements are made by the DMM6500. Since only 2-pole switching is required for this
application, one 2000-SCAN can be used to switch up to 10 resistors.
