Four-Wire Remote Sense Connection - Keithley 2281S Series Quick Start Manual

Four-wire remote sense connection

Using four-wire remote sensing connections ensures that the
programmed voltage is applied to the load and compensates
for the voltage drop in the leads between the power supply
and the load.
As shipped, the sense terminals are connected to the
output terminals by shorting jumpers. Before connecting the
wire, make sure the shorting jumpers have been removed.
When you connect the power supply for remote sensing,
the remote sense circuit detects the voltage at the sensing
points (load) and not the output terminals. The following
illustration shows the four-wire (remote sensing) DUT
connection to the rear panel.

After making the connections, slide the cover over the
rear-panel mating connector and wires.
WARNING
Failure to install the cable housing may result in
personal injury or death due to electric shock.
