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.
Rear-panel overview
The rear panel of the 2470 is shown below. Descriptions of the options follow the figure.

SENSE and FORCE
connectors
These triaxial terminals provide connections for SENSE HI and
SENSE LO, FORCE HI and FORCE LO, GUARD, and chassis
ground.
Protective earth
(safety ground)
Ground screw for connection to protective earth (safety ground).
Connect to protective earth using recommended wire size (#16
AWG or larger).
Chassis ground
Ground screw for connections to chassis ground. This provides a
connection terminal to the equipment frame.
Interlock connector
Interlock connection for use with an interlock switch, such as a
test fixture. When properly connected, the safety interlock of the
2470 places the outputs of the instrument in a safe state.
