terminal. To ensure measurement accuracy, a remote sense measurement
terminal is provided at power supply rear panel to compensate voltage drop lost
in wire.
When the power supply is used for measuring battery charge in actual
applications, the voltage drop of the wire will lead to voltage inconsistency of
both ends and inconsistency of the cutoff voltage of power supply and the
actual voltage of battery, resulting in inaccurate measurement.

Vo+,Vo-: output terminals

Vs+,Vs-: remote sense terminal
When using the remote sense function,please cut off the connection wire
between Vo+ and Vs+,so will the line between Vo- and Vs- terminals.Then
extending lines from Vs+ to the positive terminal of undertested product
and line from Vs- to the negative terminal of undertested product.
Use local sense:
Local sense doesn’t compensate the voltage drop on the connection wire, the
operation is:
1. Connect the Vo+ and Vs+ , Vo- and Vs- for short circuit using the short clips
on the back panel of the instrument or electric wire. When using local sense,
the romote sense terminal can not be disconnected.
illustrated below.
2. Connect the the positive and negative terminals of the rear panel to the
DUT.
Note
DO not disconnect the wires if remote sense is not used. Doing so will cause erratic behavior
and may damage the power supply under certain conditions
Use remote sense:
Disconnect the wires between Vo+ and Vs+, and Vo- and Vs- pins if you want
to use remote sense function.Then lead a wire from Vs+, Vs- pins and connect
to the DUT.
1. Disconnect the wires/short clips between Vo+ and Vs+, Vo- and Vs-.
2. Connect the VS+ to the DUT’s positive ( +) terminal, and connect the
VS- to the DUT’s negative ( -) terminal.
3. Connect wires from Vo+ , Vo- to the device under test.
