Local sense connection
The local sense connection is used for basic operations when
maximum precision is not required. Keep the wire as short
as possible to reduce wire resistance. If you want higher
measurement precision, use a remote sense connection.
To connect the DUT to the power supply using local
sense:
1. Connect the positive (+) terminals to the sense positive
(S+) terminals, and connect the negative (−) terminals to
the sense negative (S−) terminals to create a short circuit
using short clips or electric wire, as shown in the following
figure.
2. Connect the positive and negative terminals of the
intended channel on the front panel to the DUT, as shown
in the figure.
CAUTION
Leave remote sense wires connected, even when remote
sense is not used. Disconnecting the remote sense wires
will cause erratic behavior and may damage the power
supply.
