Figure 32: Model 2460 4-wire connections to an LED
The following figures show the physical connections for the front and rear panels. Note that you must
use either the front-panel terminals or rear-panel terminals — you cannot mix connections.
The figure below shows the front-panel connections. You can make these connections with four
insulated banana cables that are rated to the maximum current (7 A) such as two sets of the Keithley
Instruments Model 8608 High-Performance Clip Lead Set.
Turn the power to the instrument off before attaching connections to the Model 2460.
Figure 33: Model 2460 4-wire front-panel connections to an LED
The figure below shows the rear-panel connections. You can make these connections with either the
Model 2460-KIT Screw-Terminal Connector Kit (included with the Model 2460) or a Model 2460-BAN
Banana Test Leads/Adapter Cable with appropriate cabling.
