Using local sense
Configuring the power supply for local sense allows connection to the device under test with two lead
wires, but does not compensate for voltage drop in the leads.
To configure for local sense:
1. On the rear panel terminal strip, install wires between DRIVE + and SENSE +, and between
DRIVE - and SENSE -. You may also use the included shorting clip described in Rear panel at a
glance.
2. Connect to your device under test using two wires from either the front panel binding posts or the
rear panel DRIVE + and DRIVE - terminals.
