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 overprotection (OVP) circuit senses
the voltage at the sensing points (load) and not the output terminals.
Four-wire (remote sensing) DUT connection to rear panel
After making the connections, slide the cable housing over the
output mating connector and wires.
Failure to install the cable housing may result in personal injury or
death due to electric shock.
