Model 2461 Interactive SourceMeter® Instrument User's Manual Section 6: Rechargeable battery measurements
2461-900-01 Rev. A / November 2015 6-5
You can make test connections to the Model 2461 from the rear or front panel of the instrument.
Connect the FORCE HI and SENSE HI output terminals of the Model 2461 to the positive (+) terminal
of the battery. Connect the SENSE LO and FORCE LO outputs to the negative () terminal of the
battery.
Make sure that when the output of the Model 2461 is turned off, it is set to the high-impedance
(High-Z) output-off state. When the high-impedance output-off state is selected, the output relay
opens when the output is turned off. This prevents the battery from draining when the output is off.
To set the output-off state to high impedance:
1. Press the MENU key.
2. In the Source column, select Settings.
3. Select the button next to Output Off and select High Impedance.
4. Press the HOME key to return to the Home screen.
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 (10 A), such as two sets of the
Keithley Instruments Model 8608 High-Performance Clip Lead Set.

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 2461) or a Model 2460-BAN
Banana Test Leads/Adapter Cable with appropriate cabling.
