, and then the instrument power turns off automatically.
Use the rear-panel terminals
When the input current of a DUT is high, there is a voltage drop on the wires between the DUT and
output terminal of the power supply. You can use remote sense wire connections to compensate for
the voltage drop and maximize measurement accuracy.
The rear-panel terminals are shown in the following figure.
Figure 11: Remote sense connections
The terminals l and - are the positive and negative output terminals.
The terminals labeled S+ and S- are the positive and negative remote sense terminals.
There is a ground terminal for each channel on the rear panel. When a channel is enabled, its ground
terminal should be connected to a protective earth.
