Rear panel
If voltage drop in the load leads is a concern, connect the sense leads of output 1 and output 2 for 4-wire sensing as
shown in the figure on the right.

SHOCK HAZARD
Turn off AC power before making rear panel connections. All wires and straps must be properly connected
with the terminal block screws securely tightened
The power supply includes built-in relays that connect or disconnect the ± sense terminals from their corresponding
± output terminals. As shipped, the sense terminals are internally connected to the output terminals. This is referred
to as 2-wire, or local sensing.
4-wire, or remote sensing improves the voltage regulation at the load by monitoring the voltage at the load rather
than at the output terminals. This automatically compensates for the voltage drop in the load leads, which is
especially useful for CV operation with load impedance that vary or have significant lead resistance. Because remote
sensing is independent of other power supply functions, it can be used regardless of how the instrument is
programmed. Remote sensing has no effect during CC operation.
