NOTE
DO NOT jumper the sense inputs and supply outputs at the rear of the supply.
DO NOT pass the source and sense leads together in the same twisted pair.

Figure 2 shows a rear panel view of the Model 2306 detailing the connector sockets for the
battery channel “OUTPUT #1” and the charger channel “OUTPUT #2.” The Model 2306 does
not have an internal local sense connection. Therefore, the operator must connect the DUT to
the supply in either a remote or local sense configuration as illustrated. For a 4-wire remote sense
application, the sense inputs to the supply must be connected at load as close to the inputs of the
load as possible through twisted pair leads as shown in Figure 3.
On some sensitive or easily damaged devices under test (DUTs), the
instrument power-down sequence can apply transient signals to the DUT that
may affect or damage it. When testing this type of DUT, disconnect it from
the instrument before turning the instrument off.
