Function and Features

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.
