Model 2461
Interactive SourceMeter® Instrument Reference Manual Section 2:
General operation
2461-901-01 A/November 2015 2-5
LAN LED indicator
Illuminates when the instrument is connected to a local area network
(LAN).
1588 LED indicator
Illuminates when the instrument is connected to an IEEE-1588
compliant device.
1588 functionality is not supported at this time. This functionality will be made available with a
firmware update. See the Model 2461 Release Notes on the Keithley Instruments website
(http://www.keithley.com) for details.
INTERLOCK LED
indicator
Illuminates when the interlock is enabled.
Sense
terminals
Use the SENSE HI and SENSE LO terminal connections to
measure voltage at the device under test (DUT). When you use
sense leads, measurement of the voltage drop across the force
leads is eliminated. This produces more accurate voltage sourcing
and measurement at the DUT.
Force terminals
Use FORCE HI and FORCE LO terminal connections to source
or sink voltage or current to or from a device under test (DUT).
FRONT/REAR
TERMINALS switch
Activates the terminals on the front or rear panel. When the
front-panel terminals are active, a green "F" is visible to the left of
the FRONT/REAR switch. When the rear-panel terminals are
active, a yellow "R" is visible to the left of the switch.
Chassis connection
Banana jack connector that provides a chassis connection.
